Abstract:

Polymer recycling has received a great deal of attention in recent years. At the present time, small percentages of polymer wastes in Malaysia are being recycled. The recycling process has typically consisted of reprocessing the waste material to make other polymeric products or energy recovery from complete combustion. Thus, the development of concrete using non-conventional aggregates, such as polymer waste (especially polystyrene), ceramic waste, or other wastes, has been investigated to determine the comparative properties of the various concretes and the comparative costs.

Along with the development of technology to utilize waste in order to create sustainable concrete materials; therefore, this research tries to apply several artificial aggregates derived from concrete waste and fly ash. The test object was a standard concrete cylinder measuring 150 mm in diameter and 300 mm in height. Concrete was made from geopolymer coarse aggregate, treated recycled coarse aggregate, and conventional coarse aggregate. The surface hardness value was measured using a hammer test to obtain the rebound number (RN). Tests were also conducted on concrete with natural aggregate. T

Abstract:

Concrete made with large-size recycled aggregates is a new kind of recycled concrete, where the size of the recycled aggregate used is 25–80 mm, which is generally three times that of conventional aggregate. Thus, its composition and mechanical properties are different from that of conventional recycled concrete and can be applied in large-volume structures. In this study, recycled aggregate generated in two stages with randomly distributed gravels and mortar was used to replace the conventional recycled aggregate model, to observe the internal stress state and cracking of the large-size recyc

Abstract: The ongoing need for infrastructure around the world as a result of continued population growth suggests that more aggregate and cement will be needed in the manufacture of concrete. This would eventually result in greater carbon emissions, increased resource extraction, and depletion. The increasing aggregate and cement requirements are a result of the constant global demand for concrete. More extraction occurs as a result, depleting natural gravel resources and increasing CO2 emissions from quarrying operations. Construction costs and carbon emissions could both be reduced by parti

Abstract:

This experimental study describes the development of the lightweight angular fly ash aggregate (FAA) and consequent comparison of properties of FAA with natural aggregate (gravel). The manufacturing process of these FAA involves blending of fly ash with cement and alkali activators at various proportioning of cement to fly ash and placing the mix in the mould. This is followed by curing of the cubes for 7 days after letting it to dry for 24hrs and crushing them to obtain the aggregate of different sizes. After having the fly ash aggregate, the test are carried out in fresh state and hardened s

The main focus of this research is to study the strength of concrete with ceramic waste as coarse aggregate. The sources of ceramic waste are obtained from the industrial in Malaysia. Presently, in ceramics industries the production goes as waste, which is not under going the recycle process yet. The potential of recycled ceramic waste as a substitute for coarse aggregates in concrete has been investigated. The recycle ceramic waste as aggregate was used. Concrete mixes with a 28 days characteristic strength of 20 MPa were prepared using water/cement ratio of 0.4, 0.5 and 0.7. The strength dev

Concrete, the most widely used construction material, is mainly composed of coarse aggregate, fine aggregate, binding material and water. Limited natural resources have been utilized over the years for producing aggregates in the construction industry.

As a result, continuous research has been conducted on recycling CDW so that they can be used as partial replacement of conven

Abstract:

The project study with the special concrete such as light weight concrete by using pumice aggregate (Natural aggregate). One of the disadvantages of conventional concrete is having high self weight. This heavy self-weight will make it to some extent an uneconomical structural material. Light weight concrete having low density reduces dead load and increase the thermal insulation. The reduction in density is produced by using it as a replacement of coarse aggregate partially in concrete. In this Study an attempt has been made to find the compressive strength of light weight aggregate concrete u

Abstract The Recycled Aggregate (RA) obtained from C & D (Construction and Demolition) debris, especially from concrete waste is an excellent way to produce concrete sustainably and with an eco-friendly approach. The usage of RA in concrete results in savings of conventional natural materials like river sand as fine aggregate (FA) and crushed granite as coarse aggregate (CA). However, the use of recycled aggregates in concrete has shown a significant diminishment in the concrete hardened properties. Hence, this study aims to develop RA concrete that matches the properties of natural aggreg

Growing concerns about sustainability and the search for greener alternatives in construction have led to a renewed interest in recycled concrete as a building material. Recycled concrete is produced using recycled aggregates, such as construction and demolition debris, instead of virgin aggregates, which reduces the demand for natural resources and the accumulation of waste. However, the viability of recycled concrete in high-temperature applications, such as fires or exposure to extremely high temperatures, has come under critical scrutiny.
