Their system poured dry concrete mix up to four inches thick. Stone dust was spread on top of the dry mix and smoothed out. Water was then sprinkled several times and the concrete mix set up hard with the stone dust as a surface. If you did a google search on Sunset Magazine you could probably find the article.


The proportion can be 1:2:4 (M15 concrete) or 1:1.5:3 for M20 concrete. The proportion of 1:2:4 concrete denotes the ratio of cement: sand: coarse aggregates by volume unless specified. Minimum compressive strength of concrete of 1:2:4 mix proportion should be 140 kg/sq.cm or 2000 lbs/sq.in on 7 …

granite fines and further reduction in strength (i.e. 6%) at 50% replacement of granite fines in comparison with test results of nominal concrete mix of 1:1.5:3 (M-20) without granite fines. However there is no much change in flexural strength test conducted of all the variations.


Relationship Between Concrete Elements: CEMENT - SAND - STONE relationship; In practice a 50kg of cement bag contains 2 head pan of cement; this means that if i have a plan to mix 1 bag of cement my mixing ratio would be: 1:2:4 = 1 bag of cement : 4 head-pans of sand : …


1:2:4 is a rough ratio of volumes or weight, but don't mix it up as the Density of each are different. ASSUME:Concrete Density is 2400kg/m3 and a head pan is 25kg max carrying weight. A ratio of 1:2:4 gives 7 parts. Cement is 1 part therefore 1/7 of 2400 = 342kg = 6.8 x 50kg bags. Sand is 2 parts, therefore 2/7 of 2400 = 684kg. (27 head pans)


Granite stone is highly demanded by construction sector. In the processing stage, great amounts of waste powder are produced that can be used as cement replacement in concrete production.
