Experiment Study on Mechanical Properties of Plastic-Steel Fiber Reinforced Lightweight Aggregate Concrete under Freeze-Thaw Cycle
摘要
Abstract
Spherical fly ash ceramsite was selected as coarse aggregate, through the rapid freeze-thawing (0 times, 50 times, 100 times, 150 times) test about 4 groups different plastic-steel fiber(0 kg/m3, 3 kg/m3, 6 kg/m3, 9 kg/m3)content lightweight aggregate concrete, then measure the compressive strength, splitting tensile strength, flexural strength, impact resistance.The result show that: under the action of freeze-thaw, the right amount of plastic steel fiber can significantly improve the tensile strength, flexural strength of lightweight aggregate concrete;Improve the flexural compression ratio and enhance the cracking resistance of lightweight aggregate concrete;And it can significantly improve the impact resistance, but plastic-steel fiber has no much influence on the compressive strength.Comprehensive mechanical performance index, after freeze-thaw of light aggregate concrete, plastic-steel fiber optimal dosage is 6 kg/m3.关键词
