NBMCW October 2015. Hence higher value of F’ck = 68.25 N/mm2 is to be used for design calculations, As per clause number 6.2.3 Table no 6 ,page no 7 of IS 10262 : 2019For 20 mm nominal maximum size of aggregate, 0.5 percent of entrapped air of total volume of concrete. KEYWORDS: High strength concrete, silica fume, super plasticizer, admixtures. Concrete Mix Design . Exposure conditions (As per IS-456-Table-4) 8. 28 Days = 70.96. If we mention M10 concrete, it means that the concrete has 10 N/mm2 characteristic compressive strength at 28 days. So, concrete mix design can be stated as Concrete Mix = Cement:Sand:Aggregates. Design Stipulation: It is mandatory to procure user consent prior to running these cookies on your website. Rever sand is naturelly taken but crusher sand are man made its have sieve passing percentage below the river sand its possibility of use not given assurance of stength…..i know only this .. if you know lot of means share with me.. natural sand is occur from river bed from disintegration of natural rock & crush sand is produced from crushing plant ( Artificial crushing of stone. There is a requirement of design mix in high-grade concretes. 1. If site data is available then actual values of air content can also be adopted, Water content (As per Table 4 , page no 5 of IS 10262 ) for 20 mm nominal maximum size of saturated surface dry aggregate is 186 kg per cum ( for 50 mm slump without using superplasticiser ) . Hence volume of fine aggregate = 1 – 0.66 = 0.34 per unit volume of total aggregate . Contact Us | Step-6: Calculation of Mix Proportions (1) Volume of concrete = 1 m 3 (2) Volume of cement mass of cement = mass of cement/specific gravity of cement x 1/100= = 285/3.15 x 1/100 = 0.090 m 3 For Zone II 20 mm nominal maximum size aggregate, Volume of coarse aggregate and fine aggregate = 0.66 per unit volume . let me know diff. Plz I need the mix design of concrete block, M70 mix design shows it will have shrinkage cracks as the Cementitious content exceeds 450 kg as per IS 456, hello plz send me the complete calculation for any design mix, please send me the % limit of micro silica in concrete as per IS, plz. The Mix Proportion for M100 grade concrete is derived as 1 : 0.617 : 1.644 by following the design procedure given by ACI Method. Material properties1 Specific gravity of cement : 3.152 Specific gravity of coarse aggregate (at SSD conditions ) : 2.743 Specific gravity of Fine sand ( at SSD condition) : 2.654 Specific gravity of fly ash : 2.20 5. CONCRETE MIX DESIGN (GRADE M60) (a) DESIGN STIPULATION:-Target strength = 60Mpa Max size of aggregate used = 12.5 mm Specific gravity of cement = 3.15 Specific gravity of fine aggregate (F.A) = 2.6 Specific gravity of Coarse aggregate (C.A) = 2.64 Dry Rodded Bulk Density of fine aggregate = 1726 Kg/m 3 This process is usually adopted for structures which requires higher grades of concrete such as M25 and above and large construction projects where quantity of concrete consumption is huge.. Note: Mix design is same for crane bucket and pump concrete only admixture dosage will fine tuned by 0.10%. It is used as RCC (Reinforced Cement Concrete) Application/use:-1- It can be used RCC work where high compressive strength is required such as high rise buildings, long span bridges, ultra-thin white topping etc. The data required for mix proportioning is as follows. High Strength Concrete of M60 Grade for Highway Pavements for Heavy Vehicles Sanjay Srivastava*, Dr S.S Jain**, Dr M.P.S. Based on strength, concrete is classified into different grades like M5, M7.5, M10, M15, M20 etc. W/c Ratio Selected As 0.39. Absolute vol of fly ash. b. Normal temperature in the afternoon 29 degrees. This is the step where we gather all the required information for designing a concrete mix from the client. But c/s size different, because very fine particle are present in c/s. Actual site conditions vary and thus this should be adjusted as per the location and other factors. The term ‘ready mix’ is used to describe a process where concrete is pre-made at a plant and delivered in batches to job sites. Aggt: cement = 3.10 : 1, Mix proportion = 0.24:1:1.06:0.30:0.78:0.96, E. Abstract: Learn More.

Two more trials having variation of + or – 10 percent of water – cementitious material ratio shall be carried out and a graph between these water cementitious materials ratios and their corresponding strengths shall be plotted to work out the mix proportions for the given target strength for field trials . ... High strength concrete grades For M60 to M80 Grade of Concrete. These grades of concrete are used in the following sectors: a. Component of Concrete . 45.21 N/mm2 @ 3 days Cost-wise, all concrete depends primarily on two factors, namely the cost of labor and the cost of material. Minimum cement content as per is 456-2000, B. 20 Mm = 31, 10 mm = 25, r/sand = 34, c/sand = 10, (2.729*0.31) + (2.747*0.25) +(2.751* 0.34 )+(2.697*0.10) *0.619*1000 10 mm 444 kg/cum Maximum Water Cement Ratio Permitted As per MORTH Clause – 1715.2: 0.40. Click here to read complete article. = l – 0.56 = 0.44 . Hence estimated water content for 120 mm slump = 186 + ( 186 X 8.4 percent) = 202 kg/cum, As per clause number 6.2.4 , page no 7 of IS 10262: 2019, Polycarbonate ether based super plasticisers reduce water content by 30 percent or above at appropriate dosages. c/sand 174 kg/cum what will be the proportion if we want to use crush sand instead of coarse and fine aggregate? The strategy embraced to acquire the structure blend for M60 grade concrete is finished by ACI 211. Cost of concrete mix design for M50 with admixture (Approx) = Rs. 2. Plz i need. Maximum water-cement ratio 6. Absolute vol of microsilica = 0.018, Total volume of CA and FA used = 1.00-(0.143+0.036+0.018+0.02 +0.137) The “M” refers Mix and Number after M (M10, M20) Indicates the compressive strength of concrete after 28 days of curing and testing..
