Light-weight high-strength cement-based composite material
The invention relates to a light-weight high-strength cement-based composite material. By optimizing grain composition of a multi-component cementitious material and grain composition of aggregates and utilizing chemical additives such as a water reducing agent, a thickening agent and the like, the volume weight of the material can be obviously lower than that of ordinary concrete, and the compression resistive strength of 20MPa or more can be obtained. The light-weight high-strength cement-based composite material has technical advantages that under the volume weight less than or equal to 1650kg/m<3>, the compression resistive strength is greater than or equal to 20MPa after the material is standard cured for 28 days; by optimizing the grain composition of the cementing material and the grain composition of the aggregates, the construction mobility requirement can be met under a low water-binder ratio; the surface of the hardened material is compact, and the hardened material has durable performance such as permeation resistance, carbonization resistance, chlorine ion erosion resistance and the like.
