IV. MIX DESIGN STIPULATIONS FOR PROPORTIONING a) Grade designation : M30 b) Type of Cement : OPC 53 grade conforming to IS 12269 c) Maximum nominal size of aggregate : 20 mm d) Minimum cement content : 320 kg/m3
Normally our nominal mix design is based on the value of specific gravity of cement as The value will change over time if the cement is exposed to various weather conditions. So it is essential to determine the specific gravity of cement before using it.
· Concrete Mix Design for M – 20 Grade of Concrete. Following steps for concrete mix design procedure as per IS Code 10262 – 2019,. Step1 Calculate Target Mean Strength of Concrete. In order that not more than the specified proportion of test results are likely to fall below the characteristic strength, the concrete mix has to be proportioned for higher target mean compressive strength f ''ck.
· as per above results, desired strength of cement concrete m20 grade cubed mould of 7 days have been achieved as N/mm2. Therefore, above rcc mix design may be adopted as provisional design mix design for above mentioned rcc work .
Concrete Mix Design – M60 Grade Of Concrete (OPC 53 Grade) Concrete mix design – M60 grade of concrete provided here is for reference purpose only. Actual site conditions vary and thus this should be adjusted as per the loion and other factors. A. Design Stipulation: Charastaristic comprehensive Strength 28 days = 60 N/mm 2
43 Grade Portland Cement uses advanced technology to make it one of the finest. This egory of cement is ideal where the buildings may not need highlevel resistance. It''s perfect for residential and mundane commercial constructions. Some of the basic properties and prerequisite of 43 Grade Ordinary Portland Cement are listed below:.
The following materials are to be tested in the laboratory and results are to be ascertained for the design mix (a) Cement Used : OPC 53 Grade Confirming to IS 12269 (b) Fly Ash : Class F (c) Specific Gravity of Cement : (d) Specific gravity of Fly Ash: (e) Specific gravity of Silica Fume :
Mix Design Mix design mainly depends on the strength required quality of material available. The main ingredients in manufacturing solid concrete blocks are: 1) Cement 2) Fly ash 3) Crushed sand (03mm) 4) Aggregates (510mm) Typical mix design for solid concrete blocks is given below, Mix design for block grade – Mpa (target strength)
Concrete Mix Design Example – M50 Grade Concrete Grade Designation = M50 Type of cement = grade Brand of cement = Vikram ( Grasim ) Admixture = Sika [Sikament 170 ( H ) ] Fine Aggregate = ZoneII Sp. Gravity Cement = Fine Aggregate = Coarse Aggregate (20mm) = Coarse Aggregate (10mm) = Minimum Cement (As per contract) =400 kg / m 3 Maximum water .
The grades of Ordinary Portland Cement (OPC) are. (a) Grade 33. (b) Grade 43. (c) Grade 53. Grade 33 means after 28 days, the strength of this type of cement with standard must be 33 N/mm2. The ratio of cement mortar must be 1 :3 (standard cement and sand) The initial setting time of this cement is not less than 30 minutes and final setting ...
