Experimental Study on the Compressive Strength Index Conversion Relationshipof Plastic Steel Fibers Reinforced Lightweight Aggregate Concrete
摘要
Abstract
In order to study the conversion relationship on axial compressive strength and cubic compressive strength of plastic steel fibers reinforced lightweight aggregate concrete(PSFLC), cubic compressive strength and axial compressive strength were tested by 432 standard specimens respectively.The influence of the plastic steel fibers content, the water cement ratio and the type of lightweight aggregate on the compressive properties of PSFLC were investigated.The results show that the content of plastic steel fibers(5-13 kg/m3), the water cement ratio(0.32-0.4) and the type of lightweight aggregate(fc/fcu) make no difference on the ratios between axial compressive strength and cubic compressive strength.The linear equation between axial compressive strength and cubic compressive strength are obtained by regression analysis and it has good correlation.Based on analysis of regression and mathematical statistics to the ratios between axial compressive strength and cubic compressive strength, the conversion coefficient of axial compressive strength and cubic compressive strength was 0.80 for PSFLC.关键词
