Study on Properties and Proportioning Design of Foam Mixture Lightweight Soil Mixed with Fly Ash
摘要
Abstract
Based on the engineering proportion,the influence of fly ash content,foam content and water cement ratio on the properties of foam mixture lightweight soil mixed with fly ash was studied by using the control variable method.It is shown that fly ash content reduces the early strength,but improves the later strength;The wet density gradually decreases with the increase of fly ash and foam content,and increases firstly and then decreases with the increase of water cement ratio;The compressive strength decreases firstly,then slightly increases and then decreases with the increase of fly ash content,gradually decreases with the increase of foam content,and increases firstly and then decreases with the increase of water cement ratio;The ideal values of fly ash content,foam content and water cement ratio are respectively 15%～35%、600～800 L/m3 and 0.55～0.61.关键词
