(sand) are more important in the design of pumpable concrete mixes than the pro p e r ties of coarse aggre-g a t e . When combined with the ce-ment and water, fine aggregate pro-vides the fluid (mortar) which c o n v eys the large solids (coarse ag-g r egate) in suspension, thus making a mix pumpable. The fine aggregate should meet

difference between a typical 3000 PSI mix and a typical 4000 PSI mix is that there is approximately 100 pounds more of cementious material and approximately 85 pounds less sand in the 4000 pound mix. Cement is the sliding agent in concrete; while sand is abrasive which therefore, makes the 4000 pound mix pump easier.
8 ESSENTIAL QUALITY REQUIREMENTS OF PUMPED CONCRETE
Mar 21, 2016 · Concrete pumps can be either truck- or trailer mounted and range from small units, exerting pressures from 250 to 300 psi and outputs of 15 to 30 yd 3 /hr, to large units, exerting pressures of 1,000 psi and outputs up to 150 yd 3. The effective capacity of a pump depends not only on the pump itself but also on the complete system.
How to Mix Concrete in a Mixer | HowToSpecialist - How to
Start by pouring half a bucket of water (aprox. 5l) into the concrete mixer. You will determine the right amount of water with time, because the concrete should have the right consistency.
