# What do you get when you mix cement and sand and water?

**If you mix cement ,sand and water you get mortar If you mix
cement and stone pebbles or chips you get concrete
Concrete.Sometimes gravel is mixed with it, too.**

### How much water do you mix with cement mix?

A basic mixture for general use (paths, etc) is: 1 cement : 2 sand : 3 gravel by volume. Mix ingredients dry and add water until the concrete is workable. If too sloppy it may be weak, if too dry it may be difficult to work with. A basic mortar mix (brick laying, etc) is: 1 water : 2 cement : 3 sand.

### What is the cement render mix ratio for external concrete block walls?

THE MIX add your waterproofing and plasticiser to your water butt and fill with water then stir thoroughly add approx a bucket full of this mixture to your cement mixer the cement mix should be consistant and mixed to the following specs parts: cement : 4: soft washed sand :10: sharp sand :2: this gives a ratio of 3-1 a strong mix, you could use a 4-1

### Is mixing irreversible?

That depends on what is being mixed together. Two examples of this are: If you mix sand, gravel, and water it is reversible and you can separate the mixture back to its original three parts. If you mix sand, gravel, water, and cement powder it is not reversible as the water will react with the cement powder creating liquid cement and the sand and gravel will form concrete with the liquid cement. After a few…

### What is the ratiop of cement water and sand?

There are multiple mixes of concretes for different uses. A common standard mix is 3:2:1 mix 3 parts aggregate, 2 parts sand, 1 part portland cement, mixed with about 1 part water (don't make the slurry too wet), just enough to wet the material and cause it to adhere in a mass plus a little bit. A mix I like is a 3:1-1/2:1 mix. It's a little bit tougher mix. for mortar again a 3:2:1…

### What is the process of calculating quantity of cement sand metal in concrete mix design?

Choose the grade of concrete & assume minimum water/cement ratio.Conduct some initial tests on the materials like cement, sand & metal(coarse aggregate).Tests like UNIT WEGHT, SPECIFIC GRAVITY,SIEVE ANALYSIS,SLUMP CONE TEST & COMPACTION FACTOR TEST. According to the obtained results do the mix design from IS CODE of IS800-10262 check for water cement ratio & calculate the quantity of cement, sand & coarse aggregate.
