Moisture Transport in Cement Stabilised Soil Brick-Mortar Interface and Implications on Masonry Bond Strength
Abstract Interfacial bond development between masonry unit and the mortar is due to mechanical interlocking of cement hydration products into the brick pores. The paper presents results of investigations on moisture transport from fresh mortar bed to the cement-stabilised soil brick (CSSB) and its implications on the CSSB masonry bond strength. Three types of mortars (cement mortar, cement-lime mortar and cement-soil mortar) and one type of CSSB were considered in the experiments. The results show that the CSSB’s absorb moisture rapidly in the initial soaking period and attain 75% saturation in about 20 min. The fresh mortars loose considerable amount of water due to brick suction and the water–cement ratio reduces drastically in the initial one hour of contact with the bricks. Use of partially saturated (50–75%) CSSB’s for masonry construction yield maximum bond strength and is therefore recommended.
