Abstract

Alkali-activated concrete is a new type of environmentally friendly building material. The use of industrial waste marble powder to prepare alkali-activated concrete can reduce energy consumption. This study investigates the fracture properties of waste marble powder-slag-based alkali-activated concrete (WSAAC) by varying the modulus of alkali activators, sodium oxide content, and slag content through three-point bending tests, while analyzing crack development paths using DIC technology. The initial fracture toughness and unstable fracture toughness of WSAAC are positively correlated with its compressive strength. The fracture energy of WSAAC increases initially and then decreases with an increase in the modulus of alkali activators. Moreover, the fracture energy exhibits a gradual increase with higher sodium oxide and slag content.
