The bond between rebar and the concrete was examined by conducting pull out test. The pull out test was performed using 12 mm HYSD bar for M20 concrete as per IS 2770 code guidelines. The bond strength at failure (mean of 3 specimens) with river sand and Manufactured Sand as fine aggregates is 13.9MPa and 14.1MPa respectively. The bond strength ...

portland cement chemically reacts with water, and that some of the intermediate products of this reaction (that is those presen t while a portland cement product is "setting") pose a more severe hazard than does dry portland cement itself.

For normal mixing, dry blend the Portland cement and sand. Mix INTRALOK and water together, add the cement-sand mix, and then mechanically blend the complete mix thoroughly.

there IS no cement bond and shows up as white on the image in track 3 of the log. A good bond shows up as black. The top third of the log is mostly black indicating good bond.

Cement is the most widely used material in existence and is only behind water as the planet's most-consumed resource.

It is well documented that with a sand and cement ration of 5-1, and 6-1, the cement is often overstretched; i.e. not enough cement. However a 3-1 sand and cement ratio will, in most applications, bond well but incur hairline cracks or mapping. The shrinkage cracking occurs in the first few days drying.
