TITLE: Silieo-Organie Additive for Increasing Frost-Resistance of
Concrete (Kremniyorganicheskaya dobavka dl7a povysheniya

PERIODICAL: Beton i Zhelezobeton, 1959, Nr 1, pp.19-21 (USSR)
ABSTRACT: Frost-resistance of mortars and concretes can be considerably
increased by the addition of a new hydrophobic compound
GIM-94. The optimal quantity of additive recoazqnded to
secure frost-resistance is 0.1% (by weight of binder).
While this additiv% retards hardening in the initial
stages, concrete and mortar have normal strengths after
28 days. Tests with GKZL-94 (discovered by Candidate of
Technical Sciences M.N. Plungyanskaya) in the form of a
50% aqueous emulsion were carried out by ttie Laboratory
for Protection of Concrete and Reinf oreemen t from
Corrosion, of the Institute of Concrete and Reinforced
Concrete ASU SSSR (Laboratoriya zashchity betona i
armatury ot korrozii Inatituta Detona i zhelezobetona ASiA

encourage corrosion; it does not form harmful gaseous
products; it easily emulsifies In water, and emulsiun is
permanent. Tests were carried out on test cubes,
70 x 70 x 70 mm in size, 3, 7 and 28 days after appileation
of the solution mixed in the proportion of 1/3. The water
absorption was tested by submersion In water for 24 hours
of test cubes 40 x 40 x 160 mm. Previo-asly the cubes
were dried out t, a constant weight. Frost resistance
tests were carried out, by an accelerated method, by means
of freezing and defreezing of test cubes in a 5~ solution
of natrium sulphate. Results of these tests are given
in Table 1. The addition of small quantities of UKZh-94
(0.01 - 0.1% by weight of cement) has no effect on the
normal consistency of cement. When the addition roaches
0.5% or more the density increases. The time of setting
of cement increases with Increased quantity of the additive.
The addition of 0.1 - 0.01% by weight of cement sli6htly
increased the strength of samples. The addition of 0.12 -
0*2% retards the growth of strength, but after 28 days the

TITLE; Effect of Certain Organic Admixtures on the Frost Resistance of Con-
crete
PERIODICAL: Beton i zhelezobeton, 1960, No. 9, PP. 389 - 393
TEXTz Kh.M. Leybovich and M.M. Kapkin, Candidates of Technical Sciences at
NlItsement have demonstrated that by introducing the necessary quantity of silico-
organic compounds a marked increase in frost resistance can be obtained (Rpf. 1).
This has been confirmed by the works of M.N. Plungyans,kaya, Candidate of Technical
Sciences, and V.M. Moskvin, Professor (Ref. 2). In *evious works (Ref. 3) it had
been~established that the addition of rk x -94 (GKZ04~) silicoorganic liquid a
product of hydrolysis of the ethyl dichlorosilane amouiting to 0.1% of the weight
of cement increases the frost resistance of concrete 3 - 5 times. The article
describes the results of investigations pertaining to the influence of other well-
-known admixtures, such as sodium abietate (vinsol), and distillation wash from
sulfite alcohol. The experimental investigation took place in the Central Labora-

tory of Corrosion of the institut betona i zhelezobetona (Institute of Concrete
and Reinforced Concrete). The tests were made with concrete prisms 7 x 7 x 22 cm
made from Portland cement of 400 brand and puzzuolanic cement of 400 brand. Sand
and gravel (5 - 20 mm fractions) were employed as fillers. The article gives the
chemical composition of the cements. The following admixtures were used; a 50%
water emulsion of silicoorgan-tc GKZh-94 liquid, nonsaponified abietic resin in
powder form, sodium abeitute in powder folrm ( CH(3- SNV), sulfite-aleohol dregs a5
liquid concentrate. The admixtures were added to the concrete in the following
quantitiesg GK7-h-94 C.1% (based on 100% emulsion), abletic resin 0.02%. sulfite-
-alcohol dregs 0.2% (based on the dry substa..2e). After the samples had been prcc-
uced and permitted to dry during 28 days, they were sutmerged in baths with ag-
grffislve solutions in which they were kept for 4-8 hours, after which they were
altarnately frozen at -200C and defrosted at +25 - 350C during 8 hours. The de-
6ree of destructi3n of the samples was evaluated by measuring the frequen(Y of the
transversal oscillation of ~he bending of the sample on the 144MK-2 (IWEK-2)
device and by weighing the sample; this permitted to calculate the dynamic module
of Plasticity of the concrete. The durabilJty of the concrete was judged by the

number of cycles of freezing and defrosting a concrete sample could stand until
suffering a decrease of 25% in the dynamic module of elastic.~ty or a loss 0t 5%
of the original weight. A number of graphs sl~ows the influence which the above-
-cited organic admixtures have on concrete made from Portland cement and from
puzzuolanic cement. Two comparative tables give the sta-,e of durability of the
two kinds of concrete treated with different organic admixtures; the aspect of
the respective samples having undergone the tests are shown on a photograph. The
s~iperiority of the silicoorganic compound GKZh-94 over the hitherto best-known
admixtures is proved. Thn superior frost resistance obtained with GKZh-94 is main-
ly due to the development of fine-pore structure in the concrete, while the viater-
-repellent effect is only temporary-in the event of -astJng contact of concrete
L
with water. The utilization of M~-94 is recommended particularly for hydrotech-
nioal installations. There are 3 tables, 2 sets of graphs, I photograph and 3
Soviet references.

TITLE: Seismograph Frequency Characteristics cf Pulkovo (Chastotny-

FERIODICAL: Izvestiya Akademii Nauk SSSR, Seriya Geofizicheskaya,
1958, Nr 11, pp 1389-1393 (USSR)
A.BSTRACT: The seismic station "Pulkovo" received in 1951 a new
seismograph of the Kirnos-type to replace the old one of
Galitzin-type, Both apparatus operated for several years
simultaneously, It was observed that a constant interfer-
ence with the periods of 0.2-1.0 see occurred on both
seismographs. Therefore, when a reconstruction of the
building took place in 1956 a series of experiments was
made in order o find the best position for frequency
characteristics, The spectrum of interference was obtained
from 0.1 to 10 see by means of the oscillographs VEGIK (Ref.
1) and OSB-1 (Ref.2) with the galvanometers GB-11I and
GB-IV. The most frequent characteristics obtained are
shown in Table 1. An example of the spectral curve of

N-Z is represented in Fig.l., It can be seen that the
minimum of the interference is found at the point of I sec,
as represented in Fig,,2, wnich is the i3pectrum of the
horizontal components for 12 separate i3tations. A seismo-
graph can be considered as true if the amplitude of dis-
turbance is not greater-Ahan 0,2 mm. for the periods less
than 2 see and 0,5 to 0,7 mm for those of 5 sec A graph
based on this assumption is shown in Fig,3, representing
the curves of permissible magnificatioa, V and fre-
quency characteristics of seismographs of Pulkovo., The
analysis of the graph demonstrates that a broad band of
charracteristi~~s cannot give gcod results in the range of
C3

gnified about 1500 times) fall far above the curve of

permissible magnification. Therefore, to improve the
value of recording the earthquakes selected characteris-
tics should be used These were found by means of 4
pendulums. Their parameters related to the frequenc7
characteristics (Fig.3) are shown in Table 2., As it can
be seen from the table, the maximum magnification V M of
each characteristic does not differ much from the mean

result, an improvement was obtained in registration of
various seismic waves, with the better determination of
the original phase '
better disti-riction (Fig,5) and
better registration of s~;-rface waves of weak earthquakes
(Fig,6), It could be said that registration was greatly
improved, there was more exact inter-retation and a
greater number of the earthquakes wa~~ re~~orded There are

TITLE: The Use of a Seismograph With Two Galvanometers for
Tracing Earthquakes at Two Levels of Sensitivity
PERIODICAL: Izvestiya Akademii nauk SSSR, Seriya geofizicheakaya,
1960, No.10, PP-1474-1478 + I Plate
TEXT: Several seismic stations have seismographs which alter theiv
sensitivity at a given amplitude so that cscillations do not go
off-scale (Ref.1 to 4). There are two main drawbacks to this:.,
(1) mechanical failure is possible in the switching device;
(2) distortion of the trace always occurs during switching.
Since alterations in sensitivity usually take place scveral times
in the course of a single trace, much wastage therefore occurs.
It is suggested that, instead, two channels should be used, one
with a magnification ten times smaller than the other. The
present authorn.give a typical circuit including an additional
galvanometer (Fig.3). They also give the phase and frequency

characteristics of a seismograph with two galvanometers. A table
is given of the calculated instrumental constants for the two
channels. The circuit considered in this article actually has a
second galvanometer which switches in automatically for
seismograph amplitudes greater than five mIllimetres. Both the
galvanometers record on the same strip. There are 4 figures,
1 table and 5 Soviet references.

TITLE: A study of seismic noise and calculation of the optimum
seismograph constants
PERIODICAL: Studia geophysica et geodaetica, no. 3, 1961, 227-230
TEXT: The seismic-noise level in the period range from 0.1 to 5-7
sec was measured at more than 30 seismographic stations in the USSR
to find a suitable method of determining the optimum seismograph
constants. The meadurements were made with portable pendulum seismo.-
graphs consisting of a small penklum. (WEGIK system, reduced length
10=0.1 m; inertial moment K1=10- kg'm2; period variable from 0.5 to
4 sec; damping variable up to critical) and a POB-14, or a modified
OSB-1 oscillo raph (the latter designed by Borisevich) with a GB-III
galvanometer ~period 0.05 or 0.2 see, overdamped). The magnification
of this system was about 10,000 - 20,000, stable for periods up to
2-3 sec. The seismic-noise curves obtained are characterized by one
or two maxima in the period range of 0.1 - 0.6 sec, one sharp minimi4a

in the period range of 0.6 - 2.0 sec, and one or two high maxima in
the period range of 2 - 8 see. Two maxima in the latter range were
mostly found at stations located near a continental water body. The
measurements have shown that the magnification curve having a
maximum in the period range of about 1 see is the one most suitable
for high-sensitivity seismographs. It is, however, recommended that
the optimum magnification curve be calculated for each specific case,
In calculating this curve, the most essential factors are the depen-
dence of the seismic-noise amplitude on the period, and the require-
ment that the curve amplitude on the tape must not exceed a definite
limit. Paying due attention to these factors, a magnification curve
can be selected which meets the requirements of the seismograph
theory and yields the largest magnification on the tape for a given
noise level. From five characteristic points on this curve (one on
the left leg, ont-, on the right leg, and three near the top), all the
basic seismogr&.ph constants can be calculated with sufficient accuracy.

TEXT: Rational methods of determininj> the constants Tj,T2, Dl, D9, W
and V of the pendulum-galvanometer sy:3tem of an electromagnetic seismograph
are proposed. These constants entirely d3termine the form of the frequen-y
and phase response and are accepted at Soviet seismic stations as th,_-~ basi
constants of seismographs. The periol of free oscillations of the galvano-
meter T2 can be determined by a seconds timer with an error of -tot more than
1%, when- the oscillation periods of the frame of the galvanometer are shoit
it is recommended to determine T2 by recording the free oscillations of the
frame on hotographio paper. The pendulum period T, was found for the COK
(SVK), '16 (V,9Kh) and &Y11K (VEGI.K) seismographs. The measurement of
