Does concrete absorb sound?

No, concrete does not absorb sound as it very dense.


Does blue metal absorb water?

Yes, Usually it absorbs water of 0.5% to 1 % max. This is used for correcting the water content used for producing the mix concrete.


Would you expect more runoff from a parking lot or a grassy field with the same slope?

A parking lot, generally made of blacktop or concrete, would have more runoff. Grass, with earth below it, would absorb more water. Blacktop cannot be penetrated by water. Concrete can absorb water, but only a very little, especially as compared to a grassy field.


When the process of curing the concrete absorb water?

Water chemically reacts with the cement to form a new compound. The resulting concrete gradually reaches full strength over 28 days, but most of the strength comes in the first 3 days, so that is when most of the water is used and needed.

The Gravel will absorb the water until it can absorb anymore.


What rocks can absorb water?

Some rocks that are known to absorb water include sandstone, limestone, and shale. These rocks have interconnected pore spaces that allow water to be drawn in and stored within their structure.

Will Water damage concrete?

Not generally. If the concrete has a sealent on it no, but if you have a massive amount of water on unsealed concrete, the concrete will absorb the water and can make it swell and possibly crack. Answer The answer given above is totally incorrect. As far as only concrete is concerned i.e. plain concrete, the effect of water seepage is very little (depending upon the grade of concrete) whereas for RCC (reinforced cement concrete) water that seeps in corrodes the reinforcement and thus reduces the life of the structure. The defects that water seepage induces in concrete are as follows: 1) induces capillary formation (due tothe detiorating characteristics of water) 2) With this capillaries the concrete starts spalling out i.e the places where capillaries are formed, with even slight amount of stress that portion comes out and exposes the steel to the atmosphere 3) Concrete has a pH of about 12 -13. Thus it also reduces the pH of the concrete when salty water or when the concrete is exposed to marshy areas. 4) Reduces the overall strength of concrete 5) Reduces durability 6) Reduces permeabitlity to further water seepage 7) Results in ageing of structures


Why is it important to minimize the alkali metal content of concrete?

It is important to minimize the alkali metal content of concrete because concrete contains trace amounts of alkali metals like sodium and other minerals and if moisture is present then the sodium reacts with the minerals in the concrete, forming a gel and the gel may absorb water and expand causing cracks in the concrete.


Does igneous rocks absorb water?

igneous rocks do absorb water because of all the pores ,cracks, and holes in them. The holes will absorb the water and the water will get trapped in the rock there for igneous rocks do absorb water.
