What is the effect of compaction and curing on the durability of concrete?
proper compaction and proper curing of the concrete gives good concrete. for compaction, it lessen the air voids or micro space between the aggregates of the concrete, those voids are very little which is not really visible. for curing, it lessen the heat of hydration of the cement. ...

What is the effect on a plant if xylem dries up and dies?
If the xylem tissue in a plant dries up and dies, the plant will not be able to survive because the xylem tissue is responsible for transporting water and nutrients to the different parts of the plant. Without the xylem tissue to transport water and nutrients, the plant will wilt and die. ...

Why is compaction factor test better than slump test for concrete?
compaction factor test is better than slump test,because compaction factor test should have own compaction wight,so correct value will be find out from compaction factor test......... ...
What vascular tissue at transports water and minerals in plants?
Water and disolved minerals are transported by xylem from the roots through the plant. The products of photosynthesis are transported by phloem. xylem Xylem and Phloem xylem In vascular plants, water and minerals are transported by xylem cells. xylem plants dont have tissues as such. but the veins transport water and neutrience in a plant, the phleom carries glucose and the xylem carries water. Vascular tissue, specifically, xylem. the xylem carries water and the phloem carries nutrients xylem xylem xylem Xylem Tissue The vascular tissue called xylem. Xylem ...

How many types of element together make up the xylem tissue?
In Angiosperms , it is xylem vessels ( proto and meta xylem together ) , Xylem sclerenchyma and xylem parenchyma ; together form Xylem tissue ( That is why xylem is called a compound tissue ). In Gymnosperms , xylem vessels are replaced by Xylem tracheids . All other tings are almost the same . ...

What are the difference between primary xylem and secondary xylem?
primary xylem is primary in nature & is derived from procambium. But secondary xylem is secondary in nature and derived from fascicular cambium and interfascicular cambium. Primary xylem is differentiated into protoxylem and metaxylem, but secondary xylem has no such differentiation. In primary xylem vessels and tracheids are long and narrow, and vessels don't have tyloses, but in secondary xylem, vessels are blocked by tyloses, and vessels and tracheids are wider and shorter. Xylem fibres are more abundant in secondary xylem , and...

Which type of fragmentation is reduced by compaction?
External fragmentation is reduced by compaction. Compaction moves memory around until it is all placed together in one big block. ...
