Aggregates with angular particles are more difficulties to compact than one with rounded particles and therefor,requires more water in the mix to act as alubricant.this additional water, on evaporation ,tends to leave void spaces in the hardened concrete made with rounded aggregates particles which requires less water for compaction.the nature of the particles of an aggregates will also affect workability.(

How to improve the workability of concrete?
To improve the workability of concrete, issue to be concerned of as below: - increase water/cement ratio - increase size of aggregate - use well-rounded and smooth aggregate instead of irregular shape - increase the mixing time - increase the mixing temperature - use non-porous and saturated aggregate - with addition of air-entraining mixtures
What factors affect the workability of a concrete mix?
1),water content 2),mix praportions 3),size of aggregates 4),shape of aggregate 5),surface texture 6),grading of aggregates 7),use of admixture
Gauged mortar what is this used for masonry cement mortar what is this used for plasticised mortar what is this used for?
Gauged mortar is a mixture of lime and cement, typically used in bricklaying and stonework, providing better workability and adhesion than traditional lime mortars. Masonry cement mortar, which combines masonry cement and sand, is primarily used for laying bricks and blocks due to its strength and durability. Plasticised mortar contains additives that enhance its workability, making it easier to apply and shape, and is often used in projects requiring detailed finishes or complex masonry patterns.

What is the shape of a beaver?
a beaver shape of coarse!
What is important of size shape texture of coarse aggregate sa on ingredient of concrete?
so it will insure the proper mixure in the batch plant, as well as the testing goes. it has to hold so many psi's for so many hours before going to the job site
Why the aggregate supply curve has its particular shape?
The aggregate supply curve is positively sloped because at a higher price level, producers are more willing to supply more real output.
What about dry and wet impact value in aggregate test?
OBJECTIVE For determination of the aggregate impact value of coarse aggregate, which passes 12.5 mm. IS sieve and retained on 10 mm. IS sieve. Aggregate impact value test gives an indication of aggregate’s toughness property (i.e. property of a material to resist impact) Aggregate impact values are used to classify the stone aggregates with respect to toughness property as given below. The test equipment and the test procedure are quite simple and it determines the resistance to impact of stone aggregates simulating field condition. This test can be performed even at construction site or at stone quary, as the apparatus is simple and portable. Aggregate impact value test also gives an indirect indication of the strength characteristics of aggregate. Aggregate impact value of a sample also depends on the shape factors such as flakiness index and elongation index of the aggregates. It has been found that for majority of aggregates, the aggregate crushing value and aggregate impact values are numerically similar within close limits. For deciding the suitability of soft aggregates in base course construction, aggregate impact test is commonly used. A modified impact test is also often carried out in the case of soft aggregates to find the wet impact value after soaking the test sample in water. Maximum allowable aggregate impact value of aggregate in different types of pavement material / layers.
How does the shape of water affect its behavior?
water doesnt have a shape
Does the shape of a boat affect the weight it can carry?
Yes I think the shape of a boat will affect a foil boat because when you change the shape of a boat like when you make a triangle or a square it will affect the weight it can carry
