Can you fill concrete holes with concrete? If your home has concrete, you may notice holes forming due to strong weather or rodents. Most holes can be fixed with a quality mortar mix, although you should use one with a crushed stone aggregate to fill holes over 1 in (2.5 cm) deep. … Before attempting to fill a hole, clear out loose concrete and other debris.
What is the advantage of reducing water-cement ratio? Reduced drying shrinkage and cracking. Less volume change from wetting and drying. Lower permeability. Creates better bond between concrete and reinforcement.

Are bones stronger than concrete?
Are bones stronger than concrete? Well, it depends. … Bone typically has an elastic modulus that is like concrete but it’s 10 times stronger in compression. As for the stainless-steel comparison, bone has a similar compressive strength but is three times lighter.
What is the purpose of a concrete slump test?
A concrete slump test measures the consistency of a concrete batch to see how easily the concrete will flow. The test not only observes consistency between batches, but it also identifies defects in a mix, giving the operator a chance to amend the mix before it is poured on site.

A concrete slump test measures the consistency of a concrete batch to see how easily the concrete will flow. The test not only observes consistency between batches, but it also identifies defects in a mix, giving the operator a chance to amend the mix before it is poured on site.
How to secure 2×4 to concrete floor?
Powder-actuated fasteners are ideal for securing 2×4 sleepers to floors, furring strips to walls, and plywood subfloors to concrete slabs. They provide an incredibly strong and fast way to attach to concrete—but you can’t remove the nails once they’ve been fired in.
How to get rid of dust on concrete floor?

Nevertheless, by rough approximation, the melting point of concrete is about 1,500 degrees Celsius, owing to the individual melting point of its components. The melting point of quartz sand is about 1,650 degrees Celsius while the melting point of cement is approximately 1,550 degrees Celsius.
How to do exposed aggregate concrete nz?
The most common method of exposing aggregates is the ‘wash-off’ method. When the concrete has stiffened sufficiently to support a person whose footprints are no deeper than 2mm, then surface cement paste can be washed off to expose the aggregate. A medium bristle broom and continuous water spray are used.

ANSWER. ANSWER – It is possible to bond porcelain tile to a painted surface, but it isn’t recommended because the overall tile attachment is limited to the strength of the bond of the paint to the concrete. … If the paint is not well attached then as the thin-set adhesive dries and shrinks, it might pull the paint loose.
