Development activities in construction sector have caused serious problems throughout the world as the natural resource depletion and produce large amounts of waste. In Malaysia, the main problem appeared when most of the waste was abandoned and not recycling. Such conditions can cause serious problem such as environmental pollution. This research utilizes aluminum waste as sand replacement in concrete. The use of these materials not only helps in the natural resources such as sand, aggregate, cement and other building. However, it also helps in reducing the manufacturing cost of the concrete. In addition, the reduction in the cost of waste disposal, saving manpower and protect the environment from the effects of pollution are the benefits derived from the use of waste materials. A study was conducted on the use of recyclable aluminum materials, as sand replacement material in concrete mix with replacement of 1%, 2% and 5%. Lab tests, including slump tests, compressive strength and water absorption were conducted in this study. As a result, samples containing 1% aluminum waste has better performance in terms of strength and containing 5% aluminum waste has good resistance to water absorption. Using aluminum waste in concrete is an interesting way in recycling waste thus can reduce waste disposal on sites and also can conserve the natural resources.

The depletion of natural resources in the production of coarse aggregate are very crucial. Construction materials are solely depends on natural granite in the making of cement composite. Therefore, there is an urgency need to develop new alternatives material that can replace the usage of granite in concrete production. In this study, LBA have been produced to cater this problem. It is made from a mixture of bubbles from foam and ordinary portland cement. The ratio of the raw materials used is 1 part of bubbles and 2 part of ordinary Portland cement. Its manufacturing process does not involving any sintering process so it will part help to reduce energy comsuption at about 30%. The properties and characteristics of the LBA such as density, specific gravity, water absorption, strength were investigated. Results shown that the specific gravity of LBA was 1.00, water absorption was 19.44%, dry bulk density was between 730-800 kg/m3 and dry loose bulk density was ranged from 700 to 730 kg/m3 and the strength of aggregates is 14.00 MPa. It is found that the LBA can be used as a partial replacement of granite in the production of concrete.

Glass dust waste creates chronic environmental problems, mainly due to the inconsistency of waste glass streams. Glass is widely used in our lives through manufactured products such as sheet glass, bottles, glassware, and vacuum tubing. Glass is an ideal material for recycling. The use of recycled glass helps in energy saving. The increasing awareness of glass recycling speeds up inspections on the use of waste glass with different forms in various fields. One of its significant contributions is to the construction field where the waste glass was reused for concrete production. The properties of concretes containing glass dust waste as fine aggregate were investigated in this study. Glass dust waste was used as a partial replacement for sand at 10%, 20% and 50% of concrete mixes. Compression strength for 7, 14 and 28 days concrete of age were compared with those of concrete made with natural fine aggregates. The results proved that highest strength activity given by glass dust waste after 28 days. The compressive strength of specimens with 10% glass dust waste content were 32.9373 MPa, higher than the concrete control specimen at 28 days. Using glass dust waste in concrete is an interesting possibility for economy on waste disposal sites and conservation of natural resources.

Geotextile is one of material in engineering field. In this research, nonwoven geotextile is used at road shoulder to flow clean water to the drainage system since it can act as a filter. The purpose of this research are to determine the ability of nonwoven geotextile as filter media and identify the quality of the filtered water before and after placing the nonwoven geotextile. Therefore, the road shoulder is designed to show the filtering process. Based on the JKR Manual On Pavement Design, a minimum thickness for soil and aggregate is 100 mm and each layer is compacted. However, the actual thickness is not being used because it is only to show the ability of nonwoven geotextile in filtering process and its consequence of using it. Two small scale models are created, first is with nonwoven geotextile and another one is without geotextile which aims to show the difference. Tank size 350 × 200 × 240 mm is used for placing material same as road shoulder such as nonwoven geotextile, sand, soil, and aggregates which form in three layers. Water was poured in the road shoulder model. Then the water sample flow out from the tank was tested in terms of level of turbidity and suspended solids contained in the water. Base on the results, it shows that the use of nonwoven geotextile can reduce almost 100% of suspended solid and turbidity of the water from flow into drainage system. As conclusion, the use of nonwoven geotextile at road shoulder can contribute positive impact to reduce the level of water pollution.
