Effort towards preserving natural coarse aggregate for future generation and reducing cockle shell waste originating from the fisheries industry has initiated studies on possibility of integrating this waste in concrete production. This paper presents the result on the workability and compressive strength of concrete containing various percentage of cockle shell content as partial coarse aggreg...

Abstract—This work reports the potential of using Palm Kernel (PK) ash and shell as a partial substitute for Portland Cement (PC) and coarse aggregate in the development of mortar and concrete. PK ash and shell are agro-waste materials from palm oil mills, the disposal of PK ash and shell is an environmental problem of concern. The PK ash has pozzolanic properties that enables it as a partial r...

Concrete is made of coarse aggregate, fine water, cement in specific mix proportion. Coarse aggregates occupy the largest volume concrete which one most widely used construction material as per industry surveys. In order to evaluate feasibility using brick wastes aggregate producing concrete, this study was undertaken. Several million tons solid waste are produced each year due and demolition a...

This study examined the properties of fresh and hardened concretes as influenced by the moisture state of the coarse recycled concrete aggregates (RCA) after surface treatment. Surface treatment was performed by immersing the coarse RCA in a calcium metasilicate (CM) solution. The treated coarse RCA was maintained in three controlled moisture states, namely, air-dried, oven-dried, and saturated...

Pervious concrete is a green alternative to conventional pavements with minimal fine aggregate and a high void content. Pervious concrete allows water to infiltrate through the pavement, thereby reducing the runoff and the requirement for stormwater management systems. Seashell By-Products (SBP) are produced in an important quantity in France and are considered as waste. This work investigated ...
