Utilization Ceramic Wastes from Porcelain Ceramic Industry in Lightweight Aggregate Concrete

Rungroj Piyaphanuwat and Suwimol Asavapisit
Abstract—This research investigated the possibility of ceramic wastes such as deteriorated working mold (DWM) and biscuit as a coarse and fine aggregate in lightweight aggregate concrete (LWAC), which divided to two parts; effect of coarse aggregate (CA) replacement with DWM and effect of biscuit replacement fine aggregate (FA)on properties of LWAC.The ratio of ordinary Portland cement (OPC): FA: CA are 1: 2.21: 3.03 and replaced CA with DWM and FA with biscuit at the levels of 0, 25, 50, 75 and 100 wt.%. All conditions of LWAC were tested for compressive strength at 7, 14, 28 and 56 days, unit weight, water absorption and thermal conductivity at the age of 28 day. The results showed that increasing the levels of DWM decreased density and compressive strength but increased the water adsorption and thermal conductivity. At 28 days, the compressive strength and bulk density of LWAC decreased from 55.4 to 11.4 MPa and 2394 to 1362 kg/m3 with increasing of DWM replaced CA from 0 to 100 wt.%. The optimum ratio of lightweight aggregate concrete with DWM was the level of 50 wt.% that gave the compressive strength and density at 28 days of 38.1 MPa and 1803 kg/m3 respectively. This mix was collected to study the effect of biscuit replaced FA on mechanical properties. The compressive strength increased when levels of biscuit increased from 0 to 50 wt.% but decreased with the levels of biscuit excess 50 wt.%. The bulk density and thermal conductivity decreased from 1803 to 1584 kg/m3 and 0.689 to 0.592 W/m°K. The optimum mix of LWAC was found in LWAC containing 50 wt.% of DWM and 100 wt.% of biscuit that meet the ASTM C330: standard range for structural lightweight aggregate concrete.
