STRENGTH AND DURABILITY OF CONCRETES WITH A SUPER ABSORBENT POLYMER ADDITIVE
The article presents an analysis of the results of experimental studies of the effect of different types of a super absorbent polymer additive on the strength of different types of concrete. The study is aimed at the effectiveness of a new type of super absorbent additive in concrete structures. In the course of full-scale experiments, it was possible to identify the optimum dosage of SAP for fine-grained and heavy concretes. In addition, the results showed that the strength of concrete remains unchanged if the dosage of super absorbent polymer additive (SAP) is 0.5% of the weight of cement or less. The possibility of modern intelligent technologies (artificial neural networks) to predict the properties of concrete mixture and hardened concrete at given values of input parameters (SAP dosage and W/C), influence on concrete characteristics (slump of the cone, bending strength, compressive strength) has also been shown.
