Best used as a sub-base for roads underneath blocks as well as layering in between concrete or tarmac and as a hard core for projects such as car parks. 6F2; Type 3 Crushed Concrete - 0-63mm reduced fines; Oversized Clean Crushed Concrete - 75mm-100mm no fines
Basically this means the more water you use to mix the concrete very fluid the weaker the concrete mix. The less water you use to mix the concrete somewhat dry but workable the stronger the concrete mix. Accurate concrete mixing ratios can be achieved by measuring the dry materials using buckets or even a shovel. 3000 psi concrete mix ratio .

GUIDELINES ON USE OF READY MIXED CONCRETE iii Additional test for aggregates- In order to ensure that the concrete produced is as per the design mix following additional tests on aggregates are necessary. These tests will help in determining correct quantity of water and aggregates to be mixed while preparing desired mix concrete.
Add water free-water shown on the mix design – aggregate free-water For example consider a concrete mix design that calls for 282-pounds of water i.e. free-water and contains 1100 pounds of fine aggregate and 2000 pounds of coarse aggregate. The mix design shows fine aggregate absorption to be 2 and coarse aggregate absorption to be 1.
May 28 2010 Your description of the actual end use for your concrete would lead me to believe the concrete is a wet mix cast-in-place condition. Consequently consideration might be given to utilize a water reducer admixture or if the mix design permits added water to provide fresh concrete properties slump which would permit this internal method .

Our 20-40MM recycled concrete aggregate is a free draining crushed concrete with particle sizes nominally ranging between 20mm and 40mm. With minimal fines the 20-40mm aggregate is ideal for use as backfill to building sites behind retaining walls rock walls and all-weather access roads.
May 17 2017 To make ease in understanding we are finding the Concrete mix design of M20 grade concrete. The Concrete mix ratio for M20 grade of concrete is 11.53 that mean 1 part of cement 1.5 part of sand fine aggregate and 3 parts of aggregate crushed stone in volume and then batched for mixing. To know the Concrete Mix Design follow below-.
