Concrete Plasticizer it is an additive that increases the plasticity and fluidity of the concrete When SERMENT CPR100 is added to the concrete mixture it softens it Thus the workability of concrete increases which means its shelflife is up to 6 months from the date of productionRead More
Casting concrete under lowtemperature conditions is a serious challenge for the construction industry If the water in the concrete freezes the fluidity of the concrete goes wrong which willRead More
Jan 17 2017018332At 12 hours the concrete typically developed 2600psi compressive and 935psi flexural strengths the latter nearly double the threshold required for form stripping targets Each 50dolos production cycle required just over 180 yd of concrete Anthony Allega castRead More
Nov 20 2020018332The fluidity can be varied based on the SCC design With a properly designed SCC the concrete can be placed at above 5 meters height without any segregation whatsoever SSC having similar watercement ratio as of the traditional vibrated concrete will result inRead More
Fluidity of cellular concrete makes it an ideal material for filling voids underground Cellular concrete has the consistency of a thick paint so it can be pumped under pressure in voids it expands twice on average and fills the whole space including the back corners to ensure complete filling of the void applies to gas concrete onlyRead More
Concrete is a hardened building material created by combining a chemically inert mineral aggregate usually sand gravel or crushed stone a binder natural or synthetic cement chemical additives and water Plasticizing or superplasticizing agents increase the fluidity of the fresh cement mix with the same watercement ratio therebyRead More
Selfcompacting concrete SCC is a type of concrete that is produced without compaction effort in the formwork It settles by its own weight without any bleeding and segregation and behaves cohesively enough 1 The use of SCC is believed to provide various advantages such as reduced construction time labour costs and noise pollution as well as the easy filling of congested and thin sectionsRead More
