Abstract

The article presents the second stage of the investigate the effect of the modified additive on the strength characteristics of foam concrete. This work describes a method for manufacturing foam concrete samples, selects a modifying additive composition with different percentages of components, and analyzes their strength characteristics. The purpose of introducing plasticizing additives (post-alcohol bard) in foam concrete D600 to reduce water consumption and the expected increase in strength. To evaluate the changes in strength, samples were made and tested in compression at the age of 3, 7, 14, and 28 days of normal moisture curing. According to research results, the use of such additives can significantly reduce formwork removal times, increase the load-bearing capacity of structures, and expand the scope of application of foam concrete—even to structural and thermal insulation products. Additives improve not only strength but also structural uniformity, reducing the number of macropores and increasing the density of the material.
