摘要

Introducing the blast furnace slag (BFS) into grouting materials not only can improve its performances significantly but also can recycle the industrial by-product economically. The current researches related to BFS mainly focus on the preparation and evaluation of BFS-based paste (BFSBP). However, the grouting effects of hardened grout stone body with BFS-based mortar (BFSBM) are investigated rarely. In this study, a BFSBM material was developed based on BFS and its optimum mix ratio was determined. A new self-developed grouting simulation device was designed to study the grouting effects of hardened grout stone body based on different road grades and grouting diffusion radii. The results show that the optimum mix ratio of BFSBM determined as m(SS)/m(BFS), m(SH)/m(BFS), m(W)/m(BFS), and m(S)/m(BFS) are 0.11, 0.09, 0.42 and 0.4, respectively (SS, SH, W, and S represent sodium silicate, solid sodium hydroxide, purified water, and sand, respectively). BFSBM has a good grouting effect on void road bases and the highest 7d compressive strength of the core sample taken from the expressway highway void base reaches 13.2 MPa. The 7d compressive strength of the core sample 60 cm away from the grouting hole is 63.2% higher than the compressive strength in the requirements. (C) 2021 Elsevier Ltd. All rights reserved.
