description: The subject of the graduate qualification work: "High-strength light concrete for monolithic housing construction".
The research set the following goals:
1. Analysis of physical, mechanical and operational properties of heavy, light and high-strength light concretes.
2. Development of the composition of high-strength light concrete with a specific strength of more than 25, which has a low coefficient of thermal conductivity based on traditional materials.
3. Determination of its physical and mechanical characteristics.
4. Comprehensive assessment of the possibility of using high-strength light-weight concrete in monolithic housing construction for load-bearing and enclosing structures of buildings.
The work was carried out on the basis of the laboratory of building structures and materials Â«POLITEKh-SKiM-TESTÂ» of Peter the Great Saint Petersburg Polytechnic University.
The theoretical analysis of scientific literature was performed, the relevance and degree of development of the research was determined. Experimental studies were conducted to determine the main physical and mechanical properties of high-strength lightweight concrete: mobility, compressive strength, elastic modulus, shrinkage, and thermal conductivity. Since the issue of using high-strength light-weight concrete in monolithic construction is very relevant, a comparative analysis was performed based on the results of calculating two building models. The calculation was performed in the program Â«SCAD OfficeÂ», designed to calculate building structures for static, temperature and dynamic effects by the finite element method, by selecting the most dangerous combinations of forces. The calculation was performed in accordance with Russian design standards. The obtained calculation results prove that the use of high-strength lightweight concrete is economically justified when constructing monolithic buildings with a height of more than 14 stories.
