Mechanical properties of mrp lightweight concrete and effect of compressive strength on shear capacity of beams

الملخص EN

The objective of this study is to investigate the effect of compressive strength on the shear capacity of Modified Reactive Powder Lightweight Concrete (MRPLWC) Beams.

The structural behavior of (3) MRPLWC beams without web reinforcement under two point loading system, are studied.

Three percentage of Silica Fume (SF) were used to improve the compressive strength of MRPLWC.

The experimental results pointed that a positive correlation between the compressive strength and diagonal cracking load and ultimate shear load.

Increasing the compressive strength from (89.53 MPa) to (90.3) MPa lead to increase the diagonal cracking load Vcr and increasing ultimate shear load Vu.
