What factors affect the compressive strength of concrete?
water /cement ratio
What is target strength of concrete?
Target strength is the design strength which is determined by whom ever designed mixture of aggregates and the water/cement ratio.
What is mean by pcc in civil engineering?
PCC in construction refers to Plain Cement Concrete, which is used as a preparatory base for laying RCC footing. Though PCC is also concrete, this is lean in nature, the ratio being 1:4:8. The compressive strength achieved with this mix is normally 7.5kN/sq.mm.
Difference between type k cement and cement fondue?
Type K cement is slightly expansive and helps reduce the shrinkage issues associated with normal cement in concrete mixes. Cement fondu is an accelerated cement that provide concrete higher earlier strength. It does not specifically compensate for shrinkage
What is cement concrete?
Concrete actually contains cement as well as sand and gravel. We say "cement concrete" because cement is an ingredient in concrete. And because the cement is what binds together the sand and gravel that make up the concrete.
Properties of cement concrete?
Properties of fresh concrete:WorkabilitysegregationBleedingHarshnessProperties of hardened concrete:DurabilityPermeabilityCreepShrinkage
What is correlation between strength of mortar to strength of concrete?
mortar are mixing by sand & cement and concrete is mixing by cement, sand & stone
What effect has the quantity of mixing water have upon the quality of concrete?
the strength of concrete is effected by water /cement ratio as the water/cement ratio increases the strength of the concrete decreases
What is stronger concrete or cement?
Concrete is stronger than cement.It is composed of aggregates (sand and gravel) and cement; and may be cast with reinforcing bar within it (reinforced concrete). Cement is only a part of concrete. Cement has no tensile strength while concrete has compressive and tensile strength.
What are the differences between cement mortar and concrete?
Cement mortar is a mixture of cement, fine aggregate and water.Concrete is a mixture of cement, fine aggregate, coarse aggregate and water.Generally, concrete have higher strength than cement mortar.
What factors affect the compressive strength of concrete?
water /cement ratio
What is cement mad of?
Cement is hydrated limestone. Concrete is cement, stone and sand. Sometimes fiberglass fibers are added to increase strength.
Why is strength of concrete so important in construction?
The strength of concrete depends on the mix used to make it- ratio of cement, sand, gravel and water. If the mix does not produce a concrete that is strong enough, the concrete will break.
How do you create mix concrete strength C35?
concrete c35 - 1:1,5:2,5 (cement,sand,aggregate)
Which type of concrete should you use when it must reach its design strength in about 28 days?
concrete made upof ordinary portland cement gain strength in 28days
What is target strength of concrete?
Target strength is the design strength which is determined by whom ever designed mixture of aggregates and the water/cement ratio.
