Whereas, the second takes into account the moisture content and absorption of aggregates and their effect on the water content.įurthermore, this concrete mix design calculator provides the user with technical checks and notes on the same page. The first considers that the aggregates are in SSD condition, and do not contribute to the free water. In fact, this concrete mix design calculator shows you two results for the trial mixes.

The next step is to check your results on the second page. In addition to the specific gravity and dosage of admixtures, the user should specify the water reduction capacity of the water reducer at the specific dosage. And of course, the user also needs to provide basic data such as the specific gravity, moisture content, and water absorption of both aggregates.įinally, in this section, the user fills the data input in case using water-reducing admixtures and/or air-entraining agents. Then, the user selects the fineness modulus of the fine aggregates. In brief, this concrete mix design calculator allows you to select one of three types of supplementary cementitious materials.Īfterwards, the user should determine the the nominal maximum aggregate size, particle shape condition, and dry-rodded bulk density of the coarse aggregates. The user should specify the specific gravity of cement, and also that of the supplementary cementitious material in addition to its replacement percentage. Cement and supplementary cementitious materials.Step 3: Properties of constituent materials

Also, depending on the class, the user may need to specify whether the concrete is pre-stressed or not. Third, the user should select the water exposure class, whether being W0, W1, or W2.Īnd finally, in this section, the user selects the chloride exposure class. Also, depending on the class, the user may need to provide the type of concrete, whether it is plain or reinforced. Second, the user can select from the drop-down menu one of the three freeze and thaw exposure classes. Also, depending on the exposure class, the user may need to provide the type of cement. These include sulfate exposure, freeze and thaw cycles, water contact, and chloride exposure.įirst, in the sulfate exposure class drop-down menu, the user can choose one of the four exposure classes to sulfates. This section includes four major durability concerns or exposures for concrete trial mixtures. Or, if the concrete mix design is for applications such as concrete pavements, requiring a lower workability.įinally, in this section, the user can specify whether the concrete is air entrained or not. In this drop-down menu, you can choose if the placement method is by pumping, thereby requiring a higher workability. And, 1 to 2, 3 to 4, and 6 to 7 inches for imperial.Īfterwards, the user selects the special conditions, if available, which may affect the calculation process. This menu provides three ranges including 25 to 50, 75 to 100, and 150 to 175 millimeters for metric.

Then, the user can simply select the slump requirements in the next drop-down menu. However, for concrete mixtures with a known standard deviation, the user can select the second option and proceed in providing the value and number of tests. New trial mixtures usually do not have enough data to calculate the standard deviation, and thereby the user should choose the “no Data Available” option in this case.

The value must be within the limits of 15 to 45 MPa, or 2,000 to 6,000 PSI. Use this field to enter the specified compressive strength in mega-pascal or pounds per square inch. Compressive strength up to 45 MPa (metric) and up to 6000 PSI (imperial).In fact, this page can be divided into three main sections, the general data input, exposure conditions, and properties of constituent materials. As we previously mentioned, the first page is the data input page.
