INCREASING THE STRENGTH OF LIGHTWEIGHT CONCRETE AND RESEARCH OF BEAM STRUCTURES MADE FROM IT
Keywords:
lightweight concrete, beam, strength, modifiers, reinforcement, construction, experiment, modeling.Abstract
This article examines methods for increasing the strength of lightweight
concrete and the performance characteristics of beam structures made from it. During the
research, the effect of various admixtures and modifying additives on the mechanical
properties of concrete was studied. Based on the results of experimental tests and
computer modeling, the possibilities of creating load-bearing structures based on
lightweight concrete were assessed. Nowadays, increasing the strength of lightweight
concrete and using structures made from it in modern constructions is being discussed.
Opinions are given on increasing the strength of lightweight concrete and using beam
structures made from it. The bulk density, thermal conductivity, and strength of
lightweight concrete depend primarily on the properties of the fillers added to it, the
amount of water added to the mixtures, and the brand of cement. In the preparation of
lightweight concrete structures, the mixture is often placed in molds in a virgin state.
