Study on Mechanical Properties of Plant Fiber reinforced concrete Hollow Block

Abstract

In this paper, coal gangue and recycled concrete are used as some coarse aggregate instead of natural crushed stone, and plant fibers are added to improve the physical and mechanical properties of concrete. The optimum mix ratio of 28d concrete was selected from the comparative analysis of compressive strength and tensile-compression ratio. A kind of self-insulating concrete block with plant fiber was developed by designing the shape and size of the concrete block. The block has good compressive strength and low cost, can well solve environmental problems, and has good economic value and social benefits.
