Concrete is porous so you need to erect a concrete slab where drainage is not an issue. Subsurface water can cause the ground the flex, creating stress cracks in the cement. Properly preparing the subsurface helps to limit the potential for cracks in the finished concrete slab. Preparation is the most important aspect of pouring a concrete slab.

A cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel together.Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete.Concrete is the most widely used material in existence and is behind only water …
A Detailed Guide on Grading of Aggregat. This principle of formation of voids is the governing principle for the preparation of concrete under this method When the coarse aggregates are packed to make the concrete, the voids formed within the mass must be filled by some finer material Sand is used for this purpose But, there will be voids left between the sand grains too.
26-04-2017· Capping a concrete cylinder means placing a smooth uniform cap/layer at the end of a concrete cylinder to provide for a uniform load distribution when testing. Since the concrete sample will contain voids and aggregate particles at the upper surface that is left open, it is necessary to prepare a smooth uniform surface for the testing machine to press against.
Production of the clinker; Preparation of the cement ; The chemistry of cement is very complex, so cement chemist notation was invented to simplify the formula of common molecules found in cement. The raw materials for Portland cement production are a slurry of calcium oxide (44%), silicon oxide (14.5%), aluminum oxide (3.5%), ferric oxide (3%), and magnesium oxide (1.6%).

Preparation of Cement Mortar. For preparing mortar, water is added to intimate mixtures of binding material and sand The water to be used for this purpose should be free from clay, earth and other impuritiWater which is fit for drinking should only be used for preparing mortar Cement mortar may be prepared by manual mixing or by mechanical mixing.
Cement, sand, and water are the materials required for the preparation of cement mortar. Strong, sound, and durable sand and cement should be used. Water having a ph value of 6 or less is not suitable in mortar preparation. b. Mixing of Materials Mix the materials (cement, sand, and water in suitable proportion) manually or by the use of a mixer.
26-04-2017· Concrete is placed in the molds using a trowel in three layers of approximately equal depth and is remixed in the mixing pan with a shovel to prevent segregation during the molding of specimens.
