Mechanical properties of fine-grained carbonate concretes with a complex additive, including fine limestone filler and superplasticizer
The stress-strain properties of fine-grained carbonate concretes, despite the fact that they have proven themselves well in various types of construction, have not been studied to the same extent as the deformation and strength properties of traditional heavy concrete.

description | The stress-strain properties of fine-grained carbonate concretes, despite the fact that they have proven themselves well in various types of construction, have not been studied to the same extent as the deformation and strength properties of traditional heavy concrete. The object of the study is to find ways to improve the physical and mechanical properties of fine-grained carbonate concretes by using a mineral complex additive consisting of a finely dispersed limestone filler and a superplasticizer in the composition of concrete. The relationship between the ultimate values of strength characteristics (cubic strength) and crack-initiating stresses and deformations for conventional and carbonate fine-grained concrete compositions were analyzed. Through the damping mechanism of the cracking process in concrete, due to the joint work of a superplasticizer and a carbonate microdisperse filler a composition of carbonate fine-grained concrete was obtained, capable of resisting static and dynamic loads, with a dense structure and increased reliability and durability. |
