03.04.2013· Made from limestone or chalk and clay, cement provides the adhesive component in concrete and mortar. It binds the other components - aggregate and sand - together and dries to a very hard finish. The most common form of cement is Portland Grey but there is a lighter variation called Portland White. Cement is sold in 25kg (55lb) or 50kg (110lb) bags.
This paper presents the results of a study that investigated the properties of concrete made with dune sand. Different control concrete mixtures using ordinary Portland cement (OPC) with a minimum design compressive strength of 40 N/mm 2 were prepared.
Experimental Procedure. Using 2 × 4 lumber and plywood, make a form for concrete bricks. Each brick should be the same size, e.g., 4 × 4 × 20 cm. Use plywood for the bottom of the form, and 2 × 4 lumber for the sides and ends.
Sahu et al. (2003) observed that concrete made using crushed rock sand attained the comparable compressive strength, tensile strength and modulus of rupture as the control concrete. Sahul Hameed and Sekar (2009) concluded that the compressive strength, split tensile strength and the durability properties of concrete made of quarry rock dust are nearly 14% more than the conventional concrete.

Both aggregates are classified according to their grain size and are each divided into two main groups: Fine sand ...
Concrete is a composite material made of aggregate (gravel and sand), cement, and water. As a construction material, concrete can be cast in almost any shape, and once it hardens, can be a structural (load bearing) element. Portland cement may be grey or white.
Portland cement is made up of a number of compounds, but primarily consists of limestone and clay. It can be mixed with water, sand and other materials for use in building and sculpting projects.
