Shrinkage of concrete?
The loss of water results in reduction of volume of concrete this is known as shrinkage of concrete.Prevention of shrinkage in concrete:Low moisture contentSize of aggregates used.
What is the influence of calcium stearate on the shrinkage of concrete?
Calcium stearate is used to control effloresence in concrete. I don't believe there is any effect on shrinkage. However, it is often added to other concrete admixtures, like water reducers. Those products can effect shrinkage, but usually they help to reduce it.
What does shrinkage temperature steel do?
Steel bars laid in concrete to reduce cracking do to temperature change
What are types of concrete available in the Philippines?
There are quite a diverse range of concrete types in the Philippines. Some of the types of concrete in this country include Fiber-reinforced concrete, Rapid-setting concrete, Fluid-filled concrete, and Pervious concrete.
What are stress cuts in a concrete pad?
stress cuts also known as relief cuts make weak points in a concrete slab to allow for expansion and shrinkage cracks. Bascially, a concrete slab is going to crack and these cracks control where those cracks occur.

What is a shrinkage joint?
A shrinkage joint, or control joint is a separation cut with a finishing handtool into wet concrete sidewalks to 1/4 of the depth of the concrete. Since concrete shrinks a tiny bit as it cures, little tiny cracks may develop . . . the shrinkage joints make those cracks appear in the nice straight joints, thus improving the looks of the new concrete walk. Shrinkage joints may also be cut in after the concrete has cured long enough to stand on (several hours) with a concrete-cutting saw.

What pavement distress is caused mainly by asphalt concrete shrinkage and the daily temperature cycles?
block cracks

Difference between type k cement and cement fondue?
Type K cement is slightly expansive and helps reduce the shrinkage issues associated with normal cement in concrete mixes. Cement fondu is an accelerated cement that provide concrete higher earlier strength. It does not specifically compensate for shrinkage

What are the causes of concrete floor cracks?
Underlying soils movemnent. Adding to much water to concrete mix and getting shrinkage cracks. Not curing the concrete with water and it dries to fast.

stress cuts also known as relief cuts make weak points in a concrete slab to allow for expansion and shrinkage cracks. Bascially, a concrete slab is going to crack and these cracks control where those cracks occur.
Is cracking at joints acceptable after new pour of concrete?
Cracking at expansion joints is always acceptable and is the reason for the joint itself. There are two kinds of cracks, pretty ones and ugly ones! Ugly ones are random cracks where the concrete relieves itself from drying shrinkage in a random location within the slab of concrete which is normally not appealing to the eye. Expansion joints are placed at predetermined intervals within the slab where random cracks are weakened planes in locations where cracking is predicted prior to fresh concrete placement. All concrete shrinks when it dries, the larger the slab, the greater the overall shrinkage. When the tensile strength of drying shrinkage exceeds the tensile strength of the concrete, cracking will occur. Lets just hopes it cracks in a spot where we planned it instead of a location where didn't. By the way, joints should be cut at least 25% of the depth of the slab.
