Life cycle co2 emission assessment for non-steam curing precast concrete

Abstract

Researches on development of technology to reduce CO2 emission while satisfying physical properties during production of precast concrete, which is mainly applied to building structures are necessary. Accordingly, a high early strength type mixture for which removal of precast concrete form can be done by curing at room temperature instead of steam curing in the production process of precast concrete was developed. The developed high early strength type mixture was mixed with concrete to conduct coagulation, slump, and compressive strength property tests. In addition, CO2 emission and reduction performance of non-steam curing precast concrete were assessed. © (2014) Trans Tech Publications, Switzerland.
