Analysis of Drying Shrinkage of Fly Ash Aerated Concrete
To provide guiding data for the application of fly ash aerated concrete,an analysis method of drying shrinkage performance of fly ash aerated concrete is proposed.Taking the fly ash aerated concrete block produced by a manufacturer as the experimental object,four fly ash aerated concrete block walls were built according to different mortar types and curing conditions,and the shrinkage values at different block monitoring points were obtained by using a dial indicator within the age of 200 d.The experimental results show that the drying shrinkage value of fly ash aerated concrete block is highly affected by its masonry mortar type,curing conditions,environmental temperature and humidity and its initial moisture content,and under different conditions,the drying shrinkage value of fly ash aerated concrete block increases with the increase of age.The shrinkage value of fly ash aerated concrete block wall using special mortar and standard curing is low.
