压缩浇筑混凝土的应力-应变关系
Stress-strain relationship of compression-cast concrete
摘要
Abstract
Compression casting is an effective method that can significantly improve the strength and durability of concrete without the need for any chemical additives or mineral admixtures.In this paper,the concrete specimens were prepared using the compression casting method,the uniaxial compressive behavior was experimentally studied.The test results show that,compared with ordinary concrete,the compressive strength and elastic modulus of compression-cast concrete are significantly enhanced,whereas the strain at peak stress is slightly reduced.Based on the existing stress-strain model of concrete,the stress-strain model for compression-cast concrete is developed by regression of the test results.Subsequently,a model of the equivalent rectangular stress block parameters for the compression-cast flexural members is derived based on the flexural theorem,which provides theoretical basis for the flexural design and analysis of this kind of members.关键词
