The production and characteristic of lightweight bubble aggregates (LBA) are presented in this paper. The LBA are produced by
mixing between the foam and ordinary Portland cement according to the composition which has been set. Then, the characteristics of LBA such as density, water absorption, specific gravity, compressive strength, aggregate impact value and microscopic analysis of the LBA are analyzed. Those characteristics are identified in order to ensure that the LBA are
successfully categorized into lightweight aggregate. The loose bulk density is obtained at 812.5 kg/m3 which can be categorized under lightweight aggregate group. For water absorption the value obtained is 9.7 % which is slightly higher compared to normal aggregate. Meanwhile the average specific gravity obtained for the samples of LBAis 1.75. Compressive strength for the aggregates was 17.76 MPa. The highest compressive strength for LBA foamed concrete was obtained at 25% replacement with
7.83MPa. Thus, the LBA have a significant features and characteristics that can be used as coarse aggregates in concrete.

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.

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.

Rapid industrial development causes serious problem all over the world such as depletion of natural aggregates and creates enormous amount of waste material from construction and demolition activities. Quantities of polymer wastes also have been increased these recent years due to the boost in industrialization and the rapid improvement in the standard of living. In Malaysia, most of polymer wastes is abandoned and not recycled. This situation causes serious problems such as wastage of natural resources and environmental pollution. Polymer products such as synthetic fibers, plastics and rubber belong to petrochemical compound and not easily biodegradable even after a long period. One of the ways to reduce this problem is to utilize waste materials in the production of concrete. Use of these materials not only helps in getting them utilize in cement, sand, aggregate, concrete and other construction materials, it helps in reducing the cost of concrete manufacturing, but also has numerous indirect benefits such as reduction in land-fill cost, saving in energy and protecting the environment from possible pollution effects. An experimental research is made on the utilization of plastic waste, High Density Polyethylene (HDPE) as coarse aggregates in concrete with a percentage replacement of 10%, 20% and 30%. The laboratory tests include slump test, compressive strength and water absorption were conducted in this research. The samples content 10% of HDPE has better performance in term of strength.
