How to increase height of existing concrete slab? - Home .

Adding 1 inch over existing can be successful with the advise you received from Sakrete. The key step you didn't mention is the etching of any exposed old concrete. A good bond is dependent on a properly prepped base. I would always recommend etching the old base with muratic acid, neutralize and be sure to flush completely.

Bonding To Existing Concrete | Sakrete

If too much water is lost into the old concrete there will not be enough water to hydrate all of the cement particles and a lower strength material will be the result. Concrete simply will not bond to all substances. Paint, oil, glue from old flooring tiles are just a few. You must mechanically remove these materials if you want the job to last.

Slip Resistant Coatings- How to Create Non-Slip Concrete .

Any concrete surface can be slippery when it is wet or icy, especially color hardened or sealed concrete. You want your clients to be pleased with the appearance of your work, but you don't want them to slip on it and get hurt (or even to sue you), so it makes sense to understand how to make concrete slip resistant when the situation demands.

Water-to-Cement Ratio and Aggregate Moisture Corrections

May 28, 2010 · Water-to-Cement Ratio and Aggregate Moisture Corrections. . This dormant period allows for the transportation and placement of the concrete. Rather than adding additional water to increase the concrete's workability, water-reducing admixtures can improve the dispersion of the cement particles to increase the workability. .

Use of Water Reducers, Retarders, and Superplasticizer

An increase in paste quality will yield higher compressive and flexural strength, lower permeability, increase resistance to weathering, improve the bond of concrete and reinforcement, reduce the volume change from drying and wetting, and reduce shrinkage cracking tendencies (PCA, 1988).

Graphene used to make stronger, greener concrete

Increase in Strength of Concrete by Using Bottle Caps

this problem some fiber like material can be added to concrete to increase its tensile strength. Hence an attempt has been made in the present investigations to study the influence of addition of waste materials like soft drink bottle caps from workshop at a dosage of 0.25%, 0.5% and 1.0%, of total weight of concrete .

Setting Time of Concrete - Tips & Tricks | Allied Concrete

Under certain ideal conditions it is probable that concrete would continue to increase in strength indefinitely. Air temperature, ground temperature and weather conditions all play major roles in the rate with which cement hydrates. The setting time of concrete decreases with a rise in temperature, but above 30 o C a reverse effect could be .
