The Effect of Water Cement Ratio on Cement Brick Containing High Density Polyethylene (HDPE) as Sand Replacement

Abstract

Abstract. Waste disposal can contribute to the problem of environmental pollution. Most of the waste material is plastic based, because the nature of difficult of plastic degradable by itself. In order to overcome the problem, many study has been conducted on the reuse of plastic material into various field such as civil engineering and construction. In this study, municipal solid waste (MSW) in the form of High Density Polyethylene (HDPE) plastic was used to replace sand in cement sand brick production. The HDPE used in this study was obtained from a recycle factory at Nilai, Negeri Sembilan. 3% of HDPE replacement was applied in this study, with the cement-sand mix design of 1:6 and water-cement ratio 0.35, 0.40, 0.45 and 0.50 respectively. All specimens were tested for compressive strength and water absorption at 7 and 28 days. The density of the bricks was also recorded. The finding show that brick with 3% HDPE content and 0.45 of water-cement ratio at 28 days of age curing show the highest compressive strength, which is 19.5N/mm 2 compared to the control specimen of 14.4 N/mm 2 .

Influence of pandemic waste face mask on rheological, physical and chemical properties of bitumen

“…Plastic wastes can be partially used as aggregate in construction materials. Plastic waste has been used in various construction materials such as brick production [6] , [9] , [10] , [11] , coatings [12] , [13] , aggregate in concrete [14] , [15] , [16] , [17] , soil material [18] , [19] , and asphalt binder/mixture [20] , [21] , [22] , [23] , [24] , [25] , [26] , [27] .…”

Mechanical Properties of Bricks Containing Sago Fine Waste as Cement Replacement Material

“…This is due to the good rate of initial absorption is between 0.25 kg/m 2 .min to 2.00 kg/m2.min. This value can be referred to evaluate the performance of initial rate absorption on certain bricks [14,15]. Figure 6 shows a percentage graph of initial rate of absorption at curing 7 and 28 days.…”
