Mix design is a process of determining the right quality materials and their relative proportions to prepare concrete of desired properties like workability, strength, setting time and durability. While following a mix design is advised to optimise the material consumption, it is not possible at site to always come up with Mix design. Nominal mix …
Building or Renovating a House is a time consuming process and need lots of planning. One of the most tedious tasks in house construction is material procurement. There is lot of information you need before taking decision on building materials requirement for your house construction. Some of them are: Which material to buy? (Whether or not a material …
OPC 53 grade Cement OPC (Ordinary Portland Cement) is the basic form of cement with 95% cement clinkers and 5% being gypsum. Gypsum is as an additive to increase the setting time of the cement to a workable 30 minutes or more. OPC Cement gives high compressive strength at early ages and at 28 days. A 53 Grade cement gives …

Autoclaved Aerated Concrete (AAC) is Load-bearing, Light weight, High-insulating, Durable building product produced in wide range of strengths and sizes. AAC blocks also improves quality of building at the same time decrease cost of building construction. AAC bricks are made from fine ground silica sand, Fly ash, and Portland cement, Lime, water, and aluminum powder. …

Aggregate to Cement ratio is important as they are used to arrive at optimized, workable and cohesive concrete for a set of locally available concrete ingredients. In this context, the total Aggregate mean the sum of weights of Sand (Fine Aggregate) and Aggregate (usually called Coarse Aggregate) Read More : How to calculate quantities of Cement, Sand and Aggregate …

A. Bulking of Sand The volume of a given quality of Sand varies according to its moisture content. If the sand is wet, particles get a covering of water, which due to surface tension, keeps them separately and thus causes an increase in volume known as “Bulking“. Bulking increases gradually with moisture content and the …

Building Material Materials that are used for Construction Purposes are called Building Materials. Building materials can be categorized into two sources, natural and synthetic. In order to construct a good quality house in the amount you have budgeted, a thorough understanding of the quality parameters, cost and quantities of these building materials are required. Material …

Aggregate is a granular material, such as sand, gravel, crushed stone used with a cement to produce either concrete or mortar. Aggregate is relatively inexpensive and does not enter into complex chemical reactions with water; it has been customary, therefore, to treat it as inert filler in concrete and mortar. However, due to increasing awareness …

Steel reinforcement play very critical role in influencing the structural behaviour of concrete. They are strong in tension at the same time ductile enough to bent or shaped. Thermal expansion of steel and cement are approximately same. And it bonds well with the concrete.plain concrete without steel or any other reinforcement is strong in compression …

Cement is one of the oldest building materials. The word “cement” is based on the Latin word “caementum”. It is a fine, soft, powdery-type substance. The powder is so fine it can pass through a sieve capable of holding water. It is made from a mixture of elements that are found in natural materials such …
