What is a good concrete mix?
In terms of the ratio for concrete, it depends on what strength you are trying to achieve, but as a general guide a standard concrete mix would be 1 part cement to 2 parts sand to 4 parts aggregates.
For foundations, a mix of 1 part cement to 3 parts sand to 6 parts aggregates can be used..
What is the ratio of concrete slab?
A concrete mix of 1 part cement : 2 parts sand : 4 parts coarse aggregate should be used for a concrete slab. Concrete must be placed within half an hour of mixing.

What type of cement is used for walls?
Today, Portland cement remains the most common type of cement used in building materials. It is a type of “hydraulic” cement, which simply means that it will set and harden when combined with water.
How many type of cement do we have?
13 Types13 Types of Cement [PDF]: Properties, and Applications in Concrete Construction. There are various types of cement used in concrete construction. Each type of cement has its properties, uses, and advantages based on composition materials used during its manufacture.
What is the strongest cement mix?
A ratio by weight of 0.5 water, 1 cement, 3 sand, and 3 gravel should make a fine concrete, although a little less water (0.4 by weight) would make stronger concrete. The same by volume ( ie.

How thick should a concrete slab be?
4 inchesStandard concrete floor slab thickness in residential construction is 4 inches. Five to six inches is recommended if the concrete will receive occasional heavy loads, such as motor homes or garbage trucks. To prepare the base, cut the ground level to the proper depth to allow for the slab thickness.
What is the meaning of grade 20 concrete?
Grade of concrete is defined as the minimum strength the concrete must posses after 28 days of construction with proper quality control. … For example, for a grade of concrete with 20 MPa strength, it will be denoted by M20, where M stands for Mix.

What are the main components of cement?
Cement is manufactured through a closely controlled chemical combination of calcium, silicon, aluminum, iron and other ingredients. Common materials used to manufacture cement include limestone, shells, and chalk or marl combined with shale, clay, slate, blast furnace slag, silica sand, and iron ore.
Which cement is better UltraTech or ACC?
Here, UltraTech cement has highest capacity as compared to other players and hence has first rank. On the other hand, ACC having 33.4 MTPA capacity has highest capacity utilization of 33.4% and hence has scored highest points.

What is the grade of cement?
You may have heard of terms like 33 grade cement or 53 grade cement. These are terms used for describing different grades of cement. A grade of cement indicates the strength of cement that is measured in Mega pascal (Mpa) or N/mm2. Cement is usually measured after 28 days of curing for a standard cube.
Which cement is better 43 grade or 53 grade?
The fineness in cement generates early gain in strength, but along with high heat of hydration. … OPC 43 grade cement is generally used for non-structural works like plastering flooring etc. Whereas OPC 53 grade cement is used in the projects which require higher strength like concrete bridges, runways RCC works etc.
What is the best ratio for concrete mix?
The safest bet for any concrete mix is four-two-one: four parts crushed rock; two parts sand; and one part cement. The four-two-one mix, obviously, has seven parts. Conveniently, when mixing concrete, the ratio can be mixed on any range of scales.
Which grade of concrete is used for slab?
Generally M10 and M15 grades of concrete are used for leveling course, and bedding for footings. Standard concrete and concrete of grade M20 is applicable for Reinforced Cement Concrete (RCC) works for slabs, beams, columns and so on. The high strength concrete has its applications for high rise buildings.
What is a 1 2 3 mix for concrete?
Concrete is made from cement, sand, gravel and water. In making concrete strong, these ingredients should usually be mixed in a ratio of 1:2:3:0.5 to achieve maximum strength. That is 1 part cement, 2 parts sand, 3 parts gravel, and 0.5 part water.
