This is important as some concrete may need to be pumped, spread or finished. If the concrete set too quickly, it can be costly to take out. Grades of Concrete – Ratios of Concrete mix design (Cement:Sand: Aggregate) M5 1:5:10 M7.5 1:4:8 M10 1:3

The diameter of the suction pipe therefore controls the maximum size of aggregate, which can be used in a given mix of concrete to be pumped. During the 'suction stroke' the inlet valve opens and concrete is admitted into the pumping cylinder, the outlet valve remaining closed.

concrete is its mix design and deciding the type and amount of constitutes used in the making of concrete which should accomplish the necessities of the final manufactured goods. Mix design models are normally used for the function of proportioning
For the concrete mix used, maximum particle size of 16 mm and fines content 80 kilograms/cubic metre, the lowest pumping pressure was observed at a cement content of 320 kilograms/cubic metre. A lower pumpability limit was obtained at a cement content of 250 kilograms/cubic metre.
Mix Design. Mix design M40 Grade designed as per IS 10262:2009 & IS 456:2000. (FOR BANGAlORE REGION) DESIGNED By: G.PRABHAKARAN M.TECh, QA/QC ENGINEER. Mix proportioning for a concrete of M40 grade is given in A·I to A-ll. A·I STIPULATIONS FOR PROPORTIONING. a) Grade designation : M40. b) Type of cement : OPC 53 Grade conforming IS 12269.
A mix of M-80 Grade suitable for pumped concrete is to be designed with the following materials and detail. 1. OPC 53 Grade, 7-day strength 52.5 N/mm 2, Spgr 3.15 2. Silica Fume Specific Gravity 2.20 3. Standard deviation for the mix 5.0 N/mm 2 4. Grading 5.
3.1 Mix Design There are various methods of mix design. In the present work, Indian Standard method (IS: 10262 - 2009) is used for Concrete mix design of grade M20, M25, M30. 3.2 Casting of Specimens 1. Cube moulds of 150 x 150 x 150 mm are used 2.
Design a mix for pumpable concrete from the following data: 1. The max. size of coarse aggregate = 20 mm. 2. The fine aggregate passes through the 300 micron or 0.3 mm = 19%. 3. Slump of concrete …
Concrete for pumping Standard mix design procedures are used but special attention must be given such factors as aggregate grading and absorption, water content and use of admixtures BY WILLIAM C. PANARESE SENIOR CONCRETE TECHNOLOGIST
