It integrates seamlessly with the rest of the software and uses the same database to get its information. Volume of concrete required for 4 cubecasting = 4 x (0.153 x1.25) = 0.016878 m3, Weight of Cement = (384.8 x 0.016878) kg/m3 = 6.66 kg, Weight of Water = (197.4 x 0.016878) kg/m3 =3.33 kg, Weight of Coarse aggregate = (1073.33 x 0.016878) kg/m3 =18.11 kg, Weight of Fine aggregates = (790.3 x 0.016878) kg/m3 = 13.34 kg. Refer to the manufacturer to be sure the material mix design is compatible with the delivery system. Grout Calculators. Concrete”, specifically Chapter 6, “Procedure” and Appendix 1, “Metric (SI) System Adaptation. For example:  If you want to use 70% coarse aggregate #1 and 30% coarse aggregate #2 to make up your TOTAL coarse aggregate volume, simply enter “30” into the “value” column for coarse aggregate #2 “% of coarse aggregate volume” cell. The grout must be pumped until the entire annular space to be grouted is filled with grout material meeting the minimum specifications. Reports, such as “Grouting between Foundations for the Support of Equipment and Machinery” (ACI 351.1R-99), provide Actual site conditions vary and thus this should be adjusted as per the location and other factors. Coarse Aggregate Sieve Analysis Calculators, Gallon Capacity Calculator for Structures, Chloride Ion Content Calculator for Concrete Mixtures. For a mix design of concrete, we have to follow various steps, calculations, and laboratory testing to find the right mix proportions. Files > Download Concrete Mix Design EXCEL Calculator - CivilEngineeringBible.com (FREE!) Concrete Mix design of M – 20, M – 25, M – 30 and higher grade of concrete can be calculated from following steps: (a) Characteristic compressive strength of concrete required at end of 28 days  = M 25, (b) Nominal maximum size of aggregate used = 20 mm, (d) Required workability at site = 50-75 mm (slump Value), (e) Quality control is done by as per IS: 456, (f) Type of exposure Condition of concrete (as defined in IS: 456) = Mild, (g) Type of cement used = PSC conforming IS: 456 – 2000, (h) Method of placing Concrete on Site = pumpable concrete. Please note: Wastage of 5% to be allowed. Concrete mix design is the process of detrmining right proportions of cement, sand and aggregates for concrete to achieve target strength of concrete. These mix designs can be used to order from ready-mix providers or to batch onsite. S = standard deviation (N/mm2) = 4 (Refer: IS 10262- 2009 table -1), Maximum water-cement ratio taken for Mild exposure condition = 0.55, Assume water-cement ratio as 0.50 for experiment base, Maximum water content taken = 186 Kg (maximum size of aggregate = 20 mm)Correction in water content is, Estimated water content for mix = 186+ (3/100) x 186 = 191.6 kg /m3, Corrected water content for mix = 191.6 kg /m3, Minimum cement Content required for mild exposure condition = 300 kg/m3, This value is required to be checked for durability requirement from IS: 456 – 2000.

Correlation between s/c and the need of water per cubic meter. All the latest home gadgets that can make your housework easy and simple. at or near the surface due to potential voids, then additional grout may be required. Explore other calculators related to housing or building, as well as hundreds of other calculators addressing finance, math, fitness, health, and more. Foundations keyboard_arrow_right. The proportions resulting from concrete mix design are tested for their strength with the help of compressive strength test on concrete cubes and cylinders. So modifications and changes are needed in trial mix 1 to get the desired workability. This allows you to use all the raw materials information you have already stored to calculate and save your mix designs easily. The below mentioned method can be applied to any grade of concrete by changing the values. It will help you save time and hassle when creating mix designs and doing cost scenario analysis. Batch 1 & 2 used a water to grout ratio of 0.12 and Batch 3 utilized a ratio of 0.11. available for use in this design method. The calculator will indicate the number of 60 or 80 pound bags of QUIKRETE® Mortar Mix you need to construct your project with a 3/8 inch mortar joint. Which also need to satisfy durability requirement. Mar 4, 2018 - Explore Sam's board "concrete calculation" on Pinterest. In this trial mix water / cement ratio is to be decreased by 10% keeping water content constant. The most commonly shoring support, What is Rubble Masonry? Files > Download Concrete Mix Design EXCEL Calculator - CivilEngineeringBible.com (FREE!) As reduction of 0.05 in w/c, we have to increase of coarse aggregate fraction by 0.01. 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. The Advantages of concrete mix design is that it gives the right proportions of materials, thus making the concrete use economical in achieving required strength of structural members.

To increase the workability of concrete mix from 25 mm to 50-75 mm an increase in water content by +3% is to be made. F Target = 25+1.65*4. Select the desired water-to-cementitious materials ratio (water to TOTAL cementitious materials), 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”. The density of the grout should be measured before it is pumped and then pumped until the same density appears at the surface. As we assumed the aggregate is saturated surface dry condition, therefore no correction is required. Enter “0” if you do not wish to factor the moisture contents. Hence, Cement Content = (197.4/0.5) = 394.8 kg/m3. In this case standard deviation is taken from IS:456 against M 20 is 4.0. f target = f ck + 1.65 x S = 25 + 1.65 x 4.0 = 31.6 N/mm 2.
