Application of micron shell powder as fortifier for early strength of cement

Abstract

The invention relates to an application of micron shell powder as a fortifier for early strength of cement, and belongs to the field of building materials. The micron shell powder serves as a modifier for improving the early strength of the cement, so that the problem that the structural durability is reduced caused by early damages of concrete due to the fact that the early strength of an ordinary cement-based material is low is solved.

Description

technical field [0001] The invention relates to the application of micron shell powder as an early strength enhancer of cement, belonging to the field of building materials. Background technique [0002] Cement-based materials are widely used in infrastructure such as houses, bridges, and coastal dams. However, with the development of economic construction, higher requirements are placed on the performance of cement-based materials; The erosion of harmful substances will inevitably lead to the degradation of the performance of cement-based materials, resulting in initial damage to the structure, which directly affects the durability of the structure. How to improve the early performance (mechanical properties, durability) of cement-based materials is of great significance to improve the durability of concrete structures, and related research has gradually attracted the attention of civil engineering circles at home and abroad. [0003] Micron-sized shell powder is an inorga...
