On main formulae of cement stone and concrete strength

Abstract

Relation s hi p between strengt h and wa tercement ratio W/C ) has been under investigation in this·study . Generalized formula of cement stone and conc rete strengt h has been deduced . It contains (unde r certain restr i ctions ) formerly known and more simpl e fo rmulae used in practice The r e have been spec i f ied two a nt agonis tic addenda what a ll owed to establ ish the identity with in te rmolecul ar forces developed in the system . Analysis of theoretical a nd experimental data resu lted in r evea ling t he physi ca l significance of strength parameters a nd es tima t ing their numerical values. Usi ng th e extensive expe rim e ntal material , in partic ular taking as a n example heavy conc re te , t he proper corres pondence of t he experimental a nd theoretical strength estimated accord i ng to t he geeeralized formular has been s hown . Th e formular reflects variations of th e main factor (C/W) and strength parameters while approaching the value of th e predicted strength.
