Pro-tips for constructing a new concrete floor slab

Constructing a new concrete floor slab can be quite a complex exercise involving several different trades and sub-contractors. Things can go very wrong, very quickly when you are dealing with large quantities of wet concrete and you are fully exposed to the weather and adverse ground conditions.

Curing Concrete Dos and Don'ts - Bob Vila

DO spray new concrete with water. One of the most common methods for curing concrete is to hose it down frequently with water—five to 10 times per day, or as often as you can—for the first

Measurement and modeling of fresh concrete viscous

A new method is proposed to estimate pumping pressure based on concrete composition without experimental measurements. Previous studies show that the pumping pressure depends on the interface

Methods of Placing of Concrete for Various Situations

Mar 05, 2019 · How far concrete can be pumped, depends upon the various criteria such as the types of pump and the concrete mix design like workability etc. If the high-pressure pump is selected and we also give special attention to concrete mix design than concrete can be pumped to a height (vertical) over 400 m and a horizontal distance of over 2000 m

Concrete Pumping - How to Pump Cement - Concrete Network

Line length: Concrete being pumped through a line experiences friction with the internal wall of the pipeline. The longer the line, the more friction encountered. For longer pumping distances, the use of smooth-walled steel pipe can lower the resistance. The length of hose used at the end of the pipeline adds to the overall line length as well.
