High slump vs low slump concrete
Did you know?
WebFor high-quality concrete construction, a lower water-cement ratio of 0.4 is employed. For concrete construction like driveways and sidewalks, a w/c ratio ranging from 0.6 to 0.7 is normally used. The practical range of water-cement ratio ranges from 0.3 to 0.8 that gives stiff and weak concrete respectively. WebWorkability is largely determined by how fluid the concrete is. This is referred to as “Slump”. Essentially, the more fluid the concrete, the higher the slump. Although slump is often seen as an indication of water content, it is more legitimately interpreted as a measure of …
WebThe slump test is the most simple workability test for concrete, involves low cost and provides immediate results. Due to this fact, it has been widely used for workability tests … WebThe workability of pumped concrete in general have a average slump of between 50 mm and 100 mm. A concrete of less than 50 mm slumps are impractical for pumping, and slump above 125 mm should be avoided. In mixtures with high slump, the aggregate will segregate from the mortar and paste and may cause blocking in the pump lines.
WebThe slump test is the most simple workability test for concrete, involves low cost and provides immediate results. Due to this fact, it has been widely used for workability tests since 1922. The slump is carried out as per procedures mentioned in ASTM C143 in the United States, IS: 1199 – 1959 in India and EN 12350-2 in Europe .
