If you desire a secondary coarse aggregate, enter the % OF THE SECONDARY COARSE AGGREGATE TO TOTAL COARSE AGGREGATE VOLUME into the “value” cell.If you do not wish to use a second coarse aggregate, simply enter “0” into the “% of coarse aggregate volume” field.The coarse aggregate % of total aggregate volume will automatically be calculated based on the fine aggregate % entered in the previous step. Select the coarse aggregate from the drop down menu, enter the specific gravity of that coarse aggregate, and enter the total moisture content and absorption if desired. Enter “0” if you do not wish to factor the moisture contents. Enter the total moisture content (TMC) and absorption factor for your fine aggregate, if desired.Enter the specific gravity for the sand.FOR EXAMPLE: If you wish to use a ratio of 40% fine aggregate to 60% coarse aggregate, enter “40.00” in the “value” cell. Enter the TOTAL % OF FINE TO TOTAL AGGREGATE in the “value” cell.Select the type of sand from the drop down menu.Enter the specific gravities for all cementitious materials being used.Also, select the desired supplementary material from the drop down menus. If you want to implement OTHER cementitious materials besides cement, place the TOTAL WEIGHT OF ALL CEMENTITIOUS MATERIALS in the cement row for that particular substitution and enter the substitution %’s of the supplementary cementitious materials in the according rows.Enter the TOTAL WEIGHT OF ALL CEMENTITIOUS MATERIALS in the cement row (if you want straight cement, enter the total amount of cement only and place a 0 in the % by weight columns in the next three ” % of cementitious materials by weight rows”.Select the desired water-to-cementitious materials ratio (water to TOTAL cementitious materials).Start with selecting the desired air content (% of volume).
Please enter “0” in all cells to negate the moisture contents.ĮVERY “VALUE” CELL MUST BE FILLED IN ACCORDING TO THE FOLLOWING DIRECTIONS: **Moisture content and absorption cells will only change the batch weights.
