Mix Design and Pumped Concrete – Civil Engineering
A simple method of concrete mix design for pumpable concrete based on an estimated weight of the concrete per unit volume is described in the paper. The tables and figures presented are worked out by the author from a wide range of Indian materials.
Injection Grouting for Concrete Crack Repair – its Types
Injection grouting is a process of filling the cracks, voids or honeycombs under pressure in concrete or masonry structural members for repairing of cracks, strengthening of damaged concrete or masonry structural members. Grout is a flowable plastic material and should have negligible shrinkage to …

Jul 16, 2007· get the mix design or truck ticket copy, and repost. Typical masonry grout will have too high a water content since almost all of the water over a 3" slump gets absorbed into the CMU block unless it was made fluid by plasticizers and not heavy water. i’ve seen a 2" pump concrete mix installed many times for stair landings/risers.
Mix Design for Pumped Concrete with PPC, OPC, OPC+Flyash
Concretes without admixtures and of high cement content, (over about 460 kg/m 3) are liable to prove difficult to pump, because of high friction between the concrete and the pipeline.Cement contents below 270 to 320 kg/m 3 depending upon the proportion of the aggregate may also prove difficult to pump because of segregation within the pipe line.Author: Maria R.

Grouting is the application that we utilize a mix of cement and sand along with other material (such as epoxy) to fill the spaces that may result during some construction operation. for example, one type of prestressing in concrete is the post tensioning process. In this process we install tubes in concrete beam or slab then we cast
What is grouting? Why it is done? – ALLInterview
In this method of soil stabilization, soil is mixed with Portland cement and water.The mixing is done in situ by excavating soil and mixing it with cement and water by blending with mechanical mixer and sometimes fluid is injected in high pressure.
