Dependence of the Material Properties of Lightweight Cemented Soil on the Curing Temperature
Publication: Journal of Materials in Civil Engineering
Volume 26, Issue 7
Abstract
Lightweight air-trapped cemented soils are prepared by mixing air bubbles and water with sand and cement. Inappropriate curing temperatures can negatively affect the properties of lightweight air-trapped soil (ATS); however, the effect of the curing temperature has not been studied. This experimental study was conducted to investigate the effect of curing temperature on the properties of lightweight ATS. Three different unit weights of lightweight ATS, 6, 8, and , and temperatures ranging from to 40°C were considered. Based on the results of unconfined compressive strength tests, an allowable curing temperature range of 5–25°C is suggested to ensure a suitable compressive strength of lightweight ATS. Based on measurements of volume change, an allowable range of temperature that results in volume change within the permissible range is 8–25°C.
