Properties of Controlled Low-Strength Material Containing Foundry Sand

摘要

This research study was performed to document and evaluate engi- neering properties of controlled low-strength materials containing by-product foundry sand (FS-CLSM). Mixtures containing clay- bonded and chemically bonded sand were compared in the plastic and hardened states to CLSM mixtures containing uniformly graded crushed limestone sand. The data presented show that by- product foundry sand can be successfully used in CLSM, and it provides similar or better properties to that of CLSM containing crushed limestone sand.
