We are trying to achieve M30 grade concrete manually at our site. We have customized the mixture machine and have bins with load cells to tell us the weights of coarse sand, cement and 0.75 and 0.50 inch Gitti. At present we are using (1:1.80:3.5) (50kg cement : 90 kg coarse sand : 175 kg Gitti) with 28 liters water and 250 ml add mix per 50 kg cement. 7 day testing of the cubes have given 15.01 MPA...

Along with the restriction on cross section..when there is a load reversal as in the case of earthquakes there might be tension in the compression zone which will be taken care of by the reinforcement present there.

Simple, the easiest work on concrete without bleeding and segregation and place easy is called workability of concrete. There are three methods are use to determine workability of concrete 1 slump cone test 2 compaction factor test 3 vee bee test.

Abdurahman shahidi

• Jun 29th, 2017

The ease with which a concrete can be mixed, placed and finished. Wet concretes are workable but weak. Workability can be measured by the slump test, the compacting factor test, and by the V.-B. Consistometer test.

To improve the bearing capacity of soil, one of the following methods can be used.

1. Vibro Floatation Technique

2. Repalce the existing soil with road base materials and compact in layers to attain the required bearing capacity of soil.

3. Replace the existing soil with cement mix soil and compact in layers with water to attain the required bearing capacity.

4. Vibro Replacement Technique
