Dec 08 2017There are various grades of concrete available in the market based on these ratios Some of them are: M10 M20 M30 M35 etc So what really does M10 or M20 mean or represent "M" stands for "mix" Mix represents concrete with designated proportions of cement sand and aggregate Get price

How Concrete is Made

In its simplest form concrete is a mixture of paste and aggregates or rocks The paste composed of portland cement and water coats the surface of the fine (small) and coarse (larger) aggregates Through a chemical reaction called hydration the paste hardens and gains strength to form the rock-like mass known as concrete Get price

The 28

Oct 28 2013Concrete usually reaches 75% of the 28-day strength at seven days If your concrete is not reaching the proper 28-day strength I would troubleshoot each step of the process to determine why Here are example questions you can ask: Q: Is the mix design correct? A high water-cement ratio will result in a concrete with reduced strength Get price

Reinforced Cement Concrete

Reinforced cement concrete (R C C) is the combination of ordinary concrete with the reinforcement to increase its compressive and tensile strength to a great extent Concrete is a versatile material for modern construction which is prepared by mixing well-proportioned quantities of cement (even lime in some cases) sand crushed rock or gravel and water Get price

What are the Different Types of Concrete Finishes (and

The typical mix ratio of concrete is 10 to 15 percent cement 60 to 75 percent aggregate and 15 to 20 percent water You now have the basic understanding of what makes concrete next you will learn the four basic concrete finishes Slick Troweled Concrete Broom Finished Concrete Exposed Aggregate Concrete Stamped Concrete Get price

Concrete: Scientific Principles

Concrete needs to be workable so that it may be consolidated and shaped into different forms (i e walls domes etc ) walls domes etc ) Because concrete must be both strong and workable a careful balance of the cement to water ratio is required when making concrete Get price

Adding Color to Concrete

In a small container mix the concrete coloring pigment with water and then add to the concrete according to the instructions on the bag Tip: The more pigment you add the more intense the color will be Step 4 Add a little more warm water than usual to the mix so it will pour easier into the bottle Step 5 Get price

Aggregates

For a good concrete mix aggregates need to be clean hard strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the deterioration of concrete Aggregates which account for 60 to 75 percent of the total volume of concrete are divided into two distinct categories--fine and coarse Get price

Concrete: The Basic Mix

Another old rule of thumb for mixing concrete is 1 cement : 2 sand : 3 gravel by volume Mix the dry ingredients and slowly add water until the concrete is workable This mixture may need to be modified depending on the aggregate used to provide a concrete of the right workability The mix should not be too stiff or too sloppy Get price

principles of concrete mix design ppt

Concrete Mix Design -Definition Concrete mix design is defined as the appropriate selection and proportioning of constituents to produce a concrete with pre-defined characteristics in the fresh and hardened states In general concrete mixes are designed in order to achieve a defined workability strength and durability Get price

3 8 Types of Portland cement

This can be done by using mix designs that give a low permeability (mainly by keeping the w/c ratio low) and if practical by putting physical barriers such as sheets of plastic between the concrete and the soil Type III cement is designed to develop early strength more quickly than a Type I cement Get price

Why Concrete Cracks (And What To Do About It)

At the same time if you want to avoid it make sure you stick with the ratio of 5 - that means that for every pound or kilogram of cement use half a pound or kilogram of water If you want to use less you can also add a plasticizer Get price
