- W4387640642 abstract "The article presents part of the results of the study of the components of foam concrete made by the method of two-stage introduction of foam, in particular the effect of post-alcohol bard (one of the components of the modified additive of foam concrete production) on the strength of cement. The work shows the method of determining the compressive and bending strength, the selection of the components composition, the analysis and evaluation of the strength characteristics of the compared samples. The research makes it possible to determine the effect of plasticizing additive on the properties of foam concrete during their production. The purpose of introducing plasticizing additives into foam concrete is to reduce its water hardening ratio and the expected increase in strength. To estimate the strength changes the samples were made and tested in compression and bending at the age of 3, 7, 14, 21 and 28 days of normal humidity hardening. From the results of research, the additive, accelerates hardening and it was found that the additive contributes to an increase in strength, both at early age (3, 7 days) and at the design age (28 days). The results of the experiment showed that from the standpoint of improving the qualitative characteristics of the samples the use of plasticizing additives is appropriate. The additive showed optimum positive effect, so the use of this percentage of additive is the most effective to increase the compressive and flexural strength of concrete. Such high values on the strength of the specimens allow us to count on their high reliability." @default.
