Jun 02 2016 · The result is that more equidimensional fine aggregates are produced by this crushing process in comparison to other techniques such as cone jaw and roll crushers It has been shown that the more angular the shape of the fine aggregate the greater the water demand in concrete and mortars and therefore the use of impact crushers minimisesMore Details
The fineness modulus of the sand was 304 The aggregate crushing value of the coarse RCA and normal coarse aggregate were 40 and 120 MPa respectively The water absorption of the coarse and fine RCA as well as the normal coarse and fine aggregates were measured as being approximately 687 1405 060 and 416 respectivelyMore Details
21 Test result evaluation according to ČSN 73 1373 Using all valid measurements 5 at the least on one test spot arithmetic mean is calculated rounding it to 1 scale division R Particular valid measurement values must not differ from this arithmetic mean for more than ± 20 All values out of these limits are rejected remaining validMore Details
Benefits of Recycled Aggregate The use of recycled aggregate can save money for local governments and other purchasers create additional business opportunities save energy when recycling is done on site conserve diminishing resources of urban aggregates and help local governments meet the diversion goals of AB 939More Details
Standard sizes of test specimens are 4×8 in 100×200 mm or 6×12 in 150×300 mm concrete cylinders The smaller specimens tend to be easier to make and handle in the field and the laboratory A strength test result is the average of at least two strength specimens made from the same concrete sample and tested at the same ageMore Details
