“…Besides, the sand replacement with a range of 0 to 60% of limestone waste which produced from cutting and polishing activity is mixed in ratio 1:3 and 1:6 in volume and lastly evaluated their strength by [8]. There is a lot of sand replacement which utilised in mortar from waste product such as cathode ray tube glass waste [21], rubber ash [22], waste glass [23], demolished brick masonry [24], crushed rock powder [25], wood ash [26] and copper slag [27].…”

Bottom ash (BA) is a waste material which found from the electrical power plant whether collect from a boiler or landfill area. While, mortar is a construction material which incorporated between sand, cement and water. There are a lot of problems such as environmental impact and limited sources of raw material which able to solve by using waste material as a sand replacement in mortar. Thus, BA is selected and treated with fully submerging in the water to recognise as washed BA. The process is used for minimised the carbon content of the BA. Washed BA is utilised in a mortar with 5%, 10%, 15%, 20% and 25% of sand replacement and compared the result with control mix (0%) of sand replacement. The mortar design mix proportion is depended on cement to sand ratio of 1:3 with 0.55 of water-cement ratio. There are two testings, workability for fresh condition and compressive strength for hardening condition of the mortar is done. As a result, the height of the slump is reduced with increasing of the sand replacement in mortar. Additionally, the maximum load and compressive strength of the mortar is also decreased when the washed BA as a sand replacement added. Lastly, the specimen with 15% of sand replacement of washed BA is the best mortar mix which provided reasonable compressive strength and workability for further study.

“…In order to prevent environmental problems from worsening, recycling tyres is an innovative idea or way in this case [12][13][14][15][16]. Recycling tyres is the processes of recycling vehicle tyres that are no longer suitable for use on vehicles due to wear or irreparable damage (such as punctures) [17].…”

Abstract. Nowadays, uncontrolled disposal of waste materials such as tyres can affect the environment. Therefore, careful management of waste disposal must be done in order to conserve the environment. Waste tyres can be use as a replacement for both fine aggregate and coarse aggregate in the production of concrete. This research was conducted to assess the durability of concrete containing recycled tyres which have been crushed into fine fragments to replace fine aggregate in the concrete mix. This study presents an overview of the use of waste rubber as a partial replacement of natural fine aggregate in a concrete mix. 36 concrete cubes measuring 100mm x 100mm x 100mm and 12 concrete cubes measuring 150mm x 150mm x 150mm were prepared and added with different percentages of rubber from recycled tyres (0%, 3%, 5% and 7%) as fine aggregate replacement. The results obtained show that the replacement of fine aggregate with 7% of rubber recorded a compressive strength of 43.7MPa while the addition of 3% of rubber in the concrete sample recorded a high compressive strength of 50.8MPa. This shows that there is a decrease in the strength and workability of concrete as the amount of rubber used a replacement for fine aggregate in concrete increases. On the other hand, the water absorption test indicated that concrete which contains rubber has better water absorption ability. In this study, 3% of rubber was found to be the optimal percentage as a partial replacement for fine aggregate in the production of concrete.

“…Presently, huge numbers of tyres are either stored or disposed of in landfills, posing a severe ecological concern [4]. Debris tyre dumps are a major cause of habitat loss, and the tyres themselves contain poisonous and soluble materials that can seep into the groundwater and harm wildlife [5][6][7][8].…”

The importance of using recycled materials like rubber in construction materials is rising rapidly today. By incorporating used rubber into cement and mortar, we can save landfill space and reduce our dependence on natural resources. Rubber scrap can be mixed in as either fine or coarse aggregate. Add it to Portland cement for a stronger, more durable product (PC). This paper reviews the studies conducted so far on the feasibility of using waste rubber in place of conventional PC-based mortar and concrete’s natural fine aggregate. The strength and water-absorption capacity of materials made from ash from scrap rubber tyres were measured. Test results indicate that waste rubber ash was substitute with natural sand up 10% then strengths of the sample were enhanced after increasing the content of waste rubber tyre ash then strength was decreased. Water absorption capacity of samples was improved as increased the content of waste rubber tyre ash into concrete mix.
