Experimental Assessment of the Influence of Multiple Cyclic Loading on Selected Properties of Lightweight Concrete

Abstract

The paper deals with results of the experiment when ordinary and lightweight concrete was subjected to cyclic loading. Each test specimen was loaded with the force equivalent to one third of the expected compressive strength value similarly to the static modulus of elasticity test with the difference that the total number of loading cycles was nearly 4500. Dynamic modulus of elasticity and compressive strength was measured before and after cyclic loading. The result of this experiment is statistical analysis of the test results and assessment of the influence of multiple cyclic loading.
