Cockle shells used in the research were obtained from a dumping site located in a district of Perak, West Malaysia. Fig. 1 and 2 illustrates the cockle before processed by cockle trade and cockle shell which disposed as waste. The cockle shell at dumping site were packed in the gunny sack and brought to the laboratory for further processing.

Up until now Cockle Shells were discarded as waste but recent television programs have highlighted the benefits of using Cockle Shell Mulch as an aggregate. Cockle Shells are also an important component of water biofiltration systems with various water treatment works and waste processing plants opting for Cockle Shells as a filtration media.

3) To sum up the above experimental results, it is found that using splitted Cockle shells as aggregate for concrete by 10%~20% showed the same or higher compressive strength and shear strength as concretes using general aggregate and it can be used as substitute aggregate of concrete.

This paper presents the result on the workability and compressive strength of concrete containing various percentage of cockle shell content as partial coarse aggregate replacement. Concrete mixes containing 0%, 5%, 10%, 15%, 20%, 25 % and 30 % cockle shell replacement level were cast before subjected to water curing for 28 days.

As the amount of cockle shell added is increased, this rough textured material causes the mix become harsher, more difficult to be mixed thus exhibit lower slump value. This is probably credited to the variation in the texture of cockle shell which is rough than natural aggregate due to the symmetrically radial ribs running on the outer shell.

natural aggregate. Cockle shells and lime powder are used as a replacement to the coarse aggregates and cement respectively. The cockle shell waste was partially replaced as coarse aggregates by 10%, 20%, and 30%. Lime powder was replaced as cement by 5%, 10%, and 15%. M30 grade of concrete was designed and tested.

Cockle shells were partly used as a fine aggregate between range of 0% to 15% by weight of sand replacement. The specimens were casted in cube mould of size 100 mm × 100 mm × 100 mm and then cured in water for 28 days before undergoing concrete testing.

Waste shells of manila clam, cockle, clam, sea mussel, and oyster were properly crushed, sieved, and sorted to meet the requirements of the grading of standard fine aggregate. After that, the waste shells were used as partial and total replacement of the fine aggregate, and their absorption and 28-day compressive strengths of mortar were measured.

Oregon estuaries are rich with many species of clams, although only a few of these species are commonly harvested. Gaper, butter, cockle, littleneck, softshell and purple varnish clams are popularly harvested due to their abundance, size and taste. A wide variety of other bivalve species are found in Oregon estuaries, but not commonly harvested due either to their scarcity or poor taste.
