Which absorbs more water concrete or forest or wetland or grasslands?
Wetlands absorb the most water due to their high water capacity and ability to store excess water. Forests also absorb a significant amount of water through their roots and soil, followed by grasslands. Concrete does not absorb water and can actually contribute to runoff and flooding in urban areas.
Does concrete absorb sound?
No, concrete does not absorb sound as it very dense.
What difficulties arise in the use of aggregates which absorb water?
Aggregates that absorb water can lead to an increase in the water-to-cement ratio, affecting the concrete's workability and strength. This excess water absorption can also cause shrinkage and cracking in the concrete as it dries. Additionally, in freezing conditions, the water absorbed by the aggregates can freeze and expand, leading to potential damage to the concrete.
What Materials that can absorb radiation?
Materials that can absorb radiation include lead, concrete, and water. Lead is commonly used in shielding for its dense properties, concrete provides effective radiation protection due to its thickness and density, and water can act as a shield against certain types of radiation.
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.
Why does concrete absorb water?
Concrete is porous, allowing water to penetrate through micro-cracks and capillary pores within its structure. This water absorption can lead to issues such as freeze-thaw damage and corrosion of reinforcing steel if not properly sealed and maintained.
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.
Will concrete sink in water?
If the weight of the object is greater than that of an equal volume of water, it'll sink. People build boats out of concrete - it's a common assignment in civil engineering classes. If the boat will displace 1000 gallons of water but it weighs less than 8000 pounds...it'll float.
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.
What is a sentence using porous?
Concrete is porous and therefore has the ability to absorb from the surface.
Does breezeblocks absorb water?
Breezeblocks, also known as concrete masonry units (CMUs), can absorb some water due to their porous nature. However, the extent of water absorption depends on the specific type of breezeblock and its manufacturing properties. To reduce water absorption, breezeblocks can be treated with sealants or coatings. In general, while they can absorb moisture, they are not as absorbent as other materials like wood or certain types of brick.
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
