Utilization Ceramic Wastes from Porcelain Ceramic Industry in Lightweight Aggregate Concrete

Abstract

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.Index Terms-Lightweight aggregate concrete, working mold, biscuit, compressive strength, thermal conductivity. I. INTRODUCTIONLightweight concrete defined as a type of concrete which includes an expanding agent in that it increases the volume of the mixture. It is lighter than the conventional concrete that was lower than 800 kg/m3. The use of lightweight concrete has been widely spread across countries such as USA, United Kingdom, Sweden, Thailand etc. The lightweight concrete are low density and thermal conductivity. So its advantages are that there is a reduction of dead load, faster building rates in construction and lower transport and handling costs. Manuscript received October 24, 2016; revised December 20, 2016 Lightweight concrete maintains its large voids and not forming laitance layers or cement films when placed on the wall. Lightweight concretes can either be lightweight aggregate concrete, foamed concrete or autoclaved aerated concrete (AAC). Lightweight concrete blocks are often used in house construction.Lightweight aggregate concrete can be produced using a variety of lightweight aggregates. Lightweight aggregates originate from either natural materials, thermal treatment of natural raw materials, by-products from industrial. Volcanic pumice, clay, slate, shale, fly ash, oil palm shell ash, biscuit ceramics, bottom fly ash et...

Properties of eco-friendly cement mortar contained recycled materials from different sources

“…Moreover, for cement replacement mixtures, in most replacement types, the higher the replacement rate the lower density values were recorded. This can be attributed to the increase of the porosity of the mortars as a result of increasing the water to cement ratio [68] as well as to the lower specific gravity of these waste compared to the cement [69]. The reduction rates were (0.3 to 3.8%), (7 to 17.1%), (2.4 to 5%), (10.3 to 15%) for marble, granite, clay brick and porcelain powder containing mixtures respectively.…”

Mechanical Properties of lightweight Concrete Produced using Pottery Waste as Aggregate

“…This research studies the utilization of pottery waste (PW) as aggregate to produce lightweight concrete. Lightweight concrete has dry density between 800 and 2000 kg/m 3 [1] and has been used since the early Roman Empire in several structures includes the Coliseum and Cosa Port. Lightweight concrete can be obtained in three different types; no-fines concrete (concrete does not contain fine aggregate), aerated concrete, and cconcrete produced by using lightweight aggregate.…”

“…Several researches have been conducted to study the properties of lightweight concrete; some of these researches were covered. Piyaphanuwat and Asavapisit [3] studied the possibility of using ceramic tiles wastes as a coarse and fine aggregate in lightweight aggregate concrete.…”
