From 1:4 (one bag cement to 4 bag sand) to 1:6
In most cases a 3 parts aggregate to 1 part's event mixing ratio is used for quality concrete hollow block. The mixing ratio can be altered slightly.
1:4 to 1:6 ratio of cement and sand.
classification of concrete blocks
That's sort of a strange question. A concrete slab is a horizontal surface -- it's meant to be a surface you stand on or build things on. Concrete blocks are usually used for vertical surfaces -- walls. I believe that poured concrete walls are more expensive than concrete block walls. You wouldn't use concrete blocks as a substitute for a concrete slab.
the name itself says the concrete used here is of light weight.....the best example of this kind of structure is PANTHELON....
Bricks or concrete blocks
If you want to know the volume of blockfill for 8 inch blocks its 120 blocks to the cubic metre of concrete
Blocks of concrete like substance.
In India, there are standards for both hollow and solid concrete blocks. Standards include types of cement to be used and other materials added to the materials.
1:4 to 1:6 ratio of cement and sand.
most houses are made from re-inforced concrete and terracotta hollow blocks sometimes concrete
That depends on your materials. Bricks and blocks tend to be rectangles. Concrete can be any shape you would like.
Concrete
It depends on the size of the concrete blocks
The concrete blocks on the top of the hill is probably a retaining wall. Concrete blocks are used to help hold back the ground from sliding down the hill.
Concrete blocks are large cement bricks used in construction. The main purpose of concrete blocks is for building foundations, basement walls, exterior and partition walls.
