Palm oil clinker (POC), a by-product of palm oil mill, can be found in large quantity in Malaysia and it is considered as waste. POC is suitable as aggregate replacement in lightweight concrete and other engineering applications due to its physical properties.
While the terms are often used interchangeably, concrete and cement are not the same. Cement is an ingredient of concrete. It's the fine grey powder that, when mixed with water, sand and gravel or crushed stone, forms the rock-like mass known as concrete. Cement typically accounts for 10% to 12% of the concrete mixture.

4. Slumps may vary from zero for dry concrete mixes, through 50-70mm for medium workability concretes to 150mm or more for wet or harsh mixes. 5. The test is widely used as an on-site check, though it is not suitable for dry mixes which tend to give low or zero slump.-Not suitable for concrete containing aggregates larger than 40 mm.
Suitable for construction works in Bangladesh: The use of ordinary cement in concrete allows air, water and other pollutants to enter inside and corrodes reinforcements & deteriorates concrete which is not visible from outside. Crown PCC is an ideal cement whose PFA particles make dense & impermeable concrete.
It is important that water used in concrete should be free from impurities and generally, potable quality is considered best. Bore water needs to be checked before being used because it often contains impurities which affect setting times and reduce the strength of concrete. Sea water is not suitable for reinforced concrete as it causes corrosion.
In previous work focused on using recycled concrete powder as cement replacement the basic dependency of the mechanical properties on the amount of recycled concrete powder was defined. Influence of the amount of recycled concrete powder on the flexural and compressive strength was shown on 0, 33, 67 and 100 wt. % cement replacement. Based on the previous data the strength …
It is proved that the effect of stone-powder in proto-machine-made sand on concrete strength is virtually different from that of the stone powder mixed with powdered mud in ordinary machine-made sand, and the limit value of stone powder content lower than 5 % is not suitable to proto-machine-made sand for mixing concrete with grade of C50.
Portland cement is the most common type of cement in general usage, as it is a basic ingredient of concrete, mortar and most non-speciality grout. The most common use for Portland cement is in the production of concrete. Concrete is a composite material consisting of aggregate (gravel and sand), cement, and water.
