What are some ways to increase the strength of a concrete .

Now all these steps I have described is what we call mix design. So to increase the strength of your concrete, design it to your required strength by proportioning aggregate well, having a good water-cement ratio, adding additives, and finding the amount of cement needed.

Cement Additives - suppliers, manufacturers, exporters

An important raw material for cement grinding aids and strength improvement agent, improve the Dispersion, reduce the the energy consumption of electric, save time and reduce the wear and tear of the machines. It can not only improve the early strength of cement, but also improve the late strength of cement.

Plasticizer - Wikipedia

For concrete. Plasticizers or water reducers, and superplasticizers or high range water reducers, are chemical admixtures that can be added to concrete mixtures to improve workability. Unless the mix is "starved" of water, the strength of concrete is inversely proportional to the amount of water added or water-cement (w/c) ratio.

Cement Chemistry and Additives - Schlumberger

cement faces its toughest challenge under ground—in oil and gas wells where envi- ronmental conditions are far more severe than any encountered on the earth's surface. This artic e outlines the chemistry of port- land cement, the variety used to cement casings in wells and provide zona isolation, and explains how additives faci itate cement

Difference Between Additives and Admixtures – Pediaa.Com

The main difference between additives and admixtures is that additives are added to cement during manufacturing to get new properties for cement whereas admixtures are added to concrete mixtures while mixing to get new properties. References: 1. "Cement Additives." Wipertrip – Cement Additives (Function and definition), Available here. 2.

Chemical Admixtures - cement

Water-reducing admixtures usually reduce the required water content for a concrete mixture by about 5 to 10 percent. Consequently, concrete containing a water-reducing admixture needs less water to reach a required slump than untreated concrete. The treated concrete can have a lower water-cement ratio.

Seven Must-Use Concrete Admixtures (Additives)


How to Rapidly Speed Up Concrete Drying Time

Concrete dries based on ambient conditions, not on a clock, per se. Reasonable air temperatures and relative humidity in the environment are more compatible with concrete drying. This being said, measuring the moisture in the concrete is the only way to know whether the conditions in the concrete are acceptable for the finish installation.

Concrete - Wikipedia

Concrete production is the process of mixing together the various ingredients—water, aggregate, cement, and any additives—to produce concrete. Concrete production is time-sensitive. Once the ingredients are mixed, workers must put the concrete in place before it hardens.

Cement slurry design - petrowiki

The effects of the additives are reduced or enhanced by modifying the additive or by using additional additives. For most downhole requirements, more than one additive is needed. This give-and-take relationship between additives is the basis of cement-slurry design. Effects of additives
