Why grading of aggregates is important in relationship with hardened concrete?
Grading of aggregates is crucial in concrete because it influences the workability, strength, and durability of the hardened concrete. Properly graded aggregates ensure a well-packed mix that reduces voids, allowing for less cement paste and improved mechanical properties. It also affects the water-cement ratio, which is vital for achieving the desired consistency and performance of the concrete. Overall, effective grading enhances the concrete's resistance to cracking, shrinkage, and environmental factors.
How much does hardened concrete weigh?
Mass is: M=V x d.To calculate the mass you need to know the density of this concrete and also the volume.
What is supplementary cementitious material in concrete?
Supplementary cementitious materials are the mineral admixtures consisting of powdered or pulverized materials which are added to concrete before or during mixing to improve or change some of the plastic or hardened properties of Portland cement concrete.
What is the Difference between wet concrete and hard concrete?
Wet Concrete:In Wet concrete the property of the concrete is suggested based on the individual material contribution .Hardened Concrete:In Hardened concrete the property of the concrete is identified as a whole.
What is the definition of concrete nails?
Nails that are hardened for use in concrete
How coarse aggregate shape affect workability?
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.(
Wet concrete weight?
weight of hardened concrete + 100 kgf/m3

What are the properties of concrete?

How can I create round concrete forms?
To create round concrete forms, you can use a mold or formwork made of materials like wood, plastic, or metal. Simply shape the mold to the desired round shape, pour the concrete mixture into it, and allow it to set and cure. Once the concrete has hardened, remove the mold to reveal your round concrete form.
What is the literal meaning of concrete?
Originally from concretus (grown together; hardened) concrete means real or solid.
Definition of fresh concrete and Hardened Concrete?
before plcement in any mold with out compction is the fresh concrete. or just after plceing the concrete before initial setting is the fresh concrete.
