High-Strength Modified Concrete for Monolithic Construction
Intensive high-rise construction requires the improvement of existing technologies for the construction of buildings and structures, the modeling of higher quality concrete, which guarantees the safety and operational reliability of facilities. It is monolithic construction using high-strength concrete composites of a new generation based on high-quality materials, mineral powders and effective superplasticizers that will raise the level of concrete science. This work presents the possibility of obtaining high-strength concrete for monolithic construction using the complex modification of the concrete matrix with an organic and mineral component, high strength and durability results can be achieved. The effect of additives based on polyaryl and polycarboxylites on the properties of the concrete mix and concrete has been studied, and the positive effect of the mineral powder of limestone flour on the formation of the structure and properties of the composite and their interaction with microfillers of various types has been established. It has also been found that additives based on polycarboxylates have higher strength indicators. The studied compositions of concrete compositions “portland cement—filler—superplasticizer—sand—crushed stone” provide the strength characteristics of concrete of classes B 40–50.
