Feb 22, 2013· Concrete technology 1. Concrete• One of the very important and widely used material in construction• The Grade of the concrete is specified by its 28 day’s cube strength (E.g. M20 means the cube strength is 20 N/sq.mm)• Concrete used on works is specified according to IS 456 (2000).
Apr 18, 2012· Concrete Mix Design For a concrete technologist, he should have a minimum knowledge about CMD. CMD can be defined as process of selecting suitable ingredients of concrete and determining their relative proportions with object of producing concrete of certain minimum strength and durability as economically as possible.
A Basic information on different admixture for concrete Which can be used to Improved work-ability (higher slump) at given w/c ratio or Reduction of w/c ratio for a given concrete work-ability (slump).
PRECAST CONCRETE TECHNOLOGY Ready mix concrete is same as regular concrete the only difference is that it is manufactured by a automated and computerized system as per the required quantity in a centralized location. This is then delivered to the construction site in truck

Aug 03, 2016· WATER CEMENT RATIO For different ratio of concrete the amount of water for 50kg of cement is Concrete ratio Water quantity 1:3:6 34 liter 1:2:4 30 liter 1:1.5:3 27 liter 1:1:2 25 liter • In the preparation of concrete the water cement ratio is very important • For normal construction the water cement ratio is usually 0.5 • Adding to much
Concrete is the second most widely used substance after water and over six milliard tons of concrete is produced each year. Concrete is specific to different applications like new construction, repair, rehabilitation and retrofitting. Concrete building components in different sizes and shapes include wall panels, doorsills, beams, pillars and more.

3D Printing of concrete structures is se on-going high-tech developments in today’s one of the construction technology. The advantages are clear: high speed construction, no need of formwork, less heavy labour and most of all a great increase of freedom to design. This technique allows for mass
Civil Concrete Technology Lectures Notes Concrete Definition In its simplest form, concrete is a mixture of paste and aggregates (rocks). The paste, composed essentially of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. Through a series of chemical reactions called hydration, the paste hardens and gains strength to form the rock-like mass known
