and sand in the ratio of 1:1:10 respectively in 1m3? The maximum water-cement ratio to design M30 grade concrete can be found from Table 5-IS456 given above. All Rights Reserved. 3, meet the durability of the use of concrete. 4, meet the above conditions to save cement and reduce the cost of concrete. 2, meet the concrete peaceability. Hence volume of fine aggregate = 1 – 0.66 = 0.34 per unit volume of total aggregate . 1meter length square pipe how many weight ? As per IS 10262-2009 & MORT&H .

How to calculate their Maximum W/C ratio =0.45: Table 5-IS456: Adopted W/C ratio =0.45: You can reduce the water-cement ratio for M30 grade concrete based on your requirements, but remember that Water-cement ratio directly affects the strength of the concrete.

We'll assume you're ok with this, but you can opt-out if you wish. a) Grade designation : M30 b) Type of cement : OPC 53 Grade conforming IS 12269 c) Maximum nominal size of aggregate : 20mm d) Minimum cement content : 320 kg/m 3 (IS 456:2000) e) Maximum water-cement ratio : 0.45 (Table 5 of IS 456:2000) we use 16mm steel bar instead of 20mm bar, how can we Grade Designation : M30: 2. Type of Cement: OPC 53 grade confirming to IS-12269-1987: 3. Considering the durability requirements too. Maximum Nominal Aggregate Size: 20 mm: 4.

What is the concrete mixing ratio in M30 concrete if work execute by manually? Water content with using appropriate dosages of super plasticisers =186 X 0.7 =130 kg/cum From figure 1 Page no 4 of IS 10262 : 2019 free water cement ratio required for the target strength of 38.25 N/mm2 is 0.42 for PPC (curve 2) which is less than the maximum value of 0.45 prescribed for mild exposure for reinforced concrete as per Table 5 of IS 456 :2000 hence OK Hence Volume of coarse aggregate and fine aggregate = 1 – (0.112-0.134–0.0015-0.005) = As per clause number 6.2.7 , Table 10 page number 10 of IS 10262 : 2019 . of steel bars for 16mm diameter bar? And if the aggregate is dry the amount of mixing water shall be increased by an amount equal to the moisture likely to be absorbed by the Enter your email address to subscribe to this blog and receive notifications of new posts by email.Necessary cookies are absolutely essential for the website to function properly.

Please give a brief description of centre of gravity During reclamation how can the occurrence of mud waves can be rectified? for any ratio what are the volumes of soil stabilization mix of cement,lime

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 . From the grade of concrete, we can find the mixed proportion of all design concrete ratio. Exposure condition : Moderate exposure condition 5 Workability : mm 50 mm (slump) For Zone II 20 mm nominal maximum size aggregate, Volume of coarse aggregate and fine aggregate = 0.66 per unit volume . This category only includes cookies that ensures basic functionalities and security features of the website. Aggregate shall be used in saturated surface dry conditions if otherwise , when computing the requirements of mixing water , allowances shall be made for the free surface moisture contributed by the fine and coarse aggregate. For making concrete we use cement, sand, aggregate, and water which are mixed with certain ratio and concrete is cast and put in a cube of 150 mm size and put in a water bath for 28 days and afterward, it is tested in a compression test. As per IS 10262 : 2019 Table 1 and Table 2 of page no 3  As per clause number 6.2.3 Table no 6 ,page no 7 of IS 10262 : 2019 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 ) .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. The compressive stress result is known as “grade of concrete’. cut lengths?
