Why fibers are used in concrete?
to increase the strength of the material and decrease the weight of the material
What is the ratio of steel in concrete?
As per the civil engineering thumb rule, weight of steel for one cubic meter of concrete is 100kgs to 130 kgs for normal structures
What is the Density of concrete?
Density of normal concrete is in the order of about 2400 kg. per cubic metre. The densityof light-weight concrete will be less than about density 1900 kg per cubic metre.The high density concrete have unit weight ranging from about 3360 kg percubic metre to 3840 kg per cubic metre.
Wet concrete weight?
weight of hardened concrete + 100 kgf/m3
Why is reinforced concrete better than normall concrete?
reinforced concrete is better than unreinforced concrete for one major reason. concrete is an extremely strong material when it is put under pressure. however, when tension forces are introduced it will tend to fail without reinforcement. short answer: unreinforced concrete will handle a lot of weight, but it is very brittle. source: carpenter
What is the difference between a normal weight concrete and a lightweight concrete by volume?
cement is binding material while concreat is an homogeneous mixtur of cement sand and soil water etc.
Why fibers are used in concrete?

What is the wet unit weight of concrete?
unit weight= weight/volume.unit weight of normal concrete = 24 MPaIt is also known as density of concrete
Why was the tower bridge made from concrete?
It is cheap, it is strong, it is reliable, it is versatile and it is simple and easy to use. In short, there is the perfect building material.
What was the long lasting light weight building material the Romans invented?
Pumice stone mixed with concrete.
What is Siporex light weight materials?
Siporex is a lightweight, autoclaved, aerated concrete which is a completely cured, inert and stable form of calcium silicate hydrate. It is a structural material, approximately one quarter the weight of conventional concrete, composed of minute calls which give the material light weight and high thermal insulation properties.
What is the weight of a concrete truck?
Normal weight concrete weighs about 4000 lb. per cubic yard. Lightweight concrete weighs about 3000 lb. per cubic yard. If a truck is carrying 10 cubic yards, then the weight of the concrete is approximately 40,000 lb. The truck will weigh approximately 26,000 lb. for a total of 66,000 lb.

What is a pre cast concrete?
Precast concrete is a construction element made of that material and finished before its installation in the building frame. The mix of concrete must be cast or scaffolded until it gets enough strengh to handle and support own weight.
Wet concrete weight?
weight of hardened concrete + 100 kgf/m3
How much does a concrete cinder block weigh underwater?
to figure it out you just need to take the weight of the cinderblock and minus the weight of the same amount of water. to find that get a tub of water filled to the brim and put it in some thing that can catch the water that spills out when you put the cinderblock in the tub. then all you have to do is weigh the water and deduct that from the weight of the cinderblock. then the weight remaining is the weight unerwater of the cinderblock
