Birla Shakti Cement OPC 53 Grade, Packaging Type: PP

Final Setting Time : 265 minutes : Area Density : 266 m2 /kg : Minimum Order Quantity : 120 Bag : Product Description. 43 Grade OPC Birla Shakti Cement is most commonly used cement for a wide range of applications like dry-lean mixes, general-purpose ready-mixes, high strength pre-cast and concrete. We are backed by a team of professionals who

Minimum cement content as per is 456-2000. B. Test data for concrete ingredients Specific gravity of cement = 3.15 Specific gravity of fly ash = 2.24 Specific gravity of microsilica = 2.21 Setting time of cement initial = 120 min, final = 185 min Cement compressive strength = 45.21 N/mm 2 @ 3 days 54.82 N/mm 2 @ 7 days 69.32 N/mm 2 @ 28 days

10150 psi. Grades of concrete, mainly classified in three categories as follows. 1- Lean concrete. 2- Ordinary grade of concrete. 3- Standard grade of concrete. 4- High strength concrete grades. 1- Lean concrete. Lean concrete is a mix where the amount of cement is lower than the amount of liquid present in the strata.

Cement on the Go Portland Cement, Concrete, and Heat of Hydration Fig.1 demonstrates the effect of element size on concrete tempera-ture with time due to the heat of hydration. Temperature rises of 55 C (100 F) have been observed with high ce-ment content mixes.(2) These tem-perature rises cause expansion while the concrete is hardening. If

Jun 14, 2018 10. EFFECT OF TIME ON SETTING OF CEMENT MORTAR Time has an important role on strength of developed cement mortar. When a cement mixture in the ratio of 1:3 with water is allowed to dry, the strength of solid mass keeps on increasing with the time given for setting. It acquires a nearly full strength in 28 days.

Jan 01, 2019 The cement used was of uniform colour (grey with a light greenish shade), free from any hard lumps. Table-1 summarises the results of tests conducted on cement in accordance with procedure laid down in IS 8112: 1989 [8] Table-1: Physical properties of Grade 43 Portland cement. S. No.

Feb 16, 2017 53 Grade cement has high heat of hydration. So it requires good curing. But we advice to use 53 grade cement only for all RCC applications like beams, columns, slabs etc., For plastering, tiling, brick work etc., go with PPC, PSC or other grades (43 grade) etc., cement. We don’t comment on any specific brand. Our blog is self explanatory.

Jan 14, 2005 If it is 53-grade cement, then the setting time is low and, therefore, the curing time brief. This also requires a lot of water. If PPC is used, then the setting is gradual, but it is more durable. So the consumers need to understand whether they want cement that sets quickly or

Oct 06, 2017 Significance of calculating Initial and final setting time of cement:-. Well, After mixing cement with water, it takes time to place the cement paste in position, initial setting time possess a primary role in strength & it is mandated that cement paste or concrete is placed in position before it crosses initial setting time

43 Grade Ordinary Portland Cement 43 grades of cement are used where high early strength in 1 to 28 days range is required. These days the ‘Structural Engineers’ propose these cements mainly for RCC works where a member takes high tensile stress.

The setting time of concrete decreases with a rise in temperature, but above 30 o C a reverse effect could be observed. At low temperatures setting time is retarded. Proper curing techniques and site preparation will aid the setting time. However when concrete is being used in times of temperature extremes, i.e. colder weather or in the middle

Aug 14, 2010 The initial setting time of Grade 43 Cement was 155 minutes but the Grade 53 had initial setting time of 120 minutes. Comparison of the 3 days, 7 days and 28 days compression tests of the above two varieties of indicated that the strength was 22% higher at 3 days, 17% higher at 7 days and 5% higher at 28 days test intervals for the Grade 53

Setting time of cement: When cement is mixed with water, it hydrates and makes cement paste. This paste can be moulded into any desired shape due to its plasticity. Read More

Feb 02, 2017 OPC (Ordinary Portland Cement) is the basic form of cement with 95% cement clinkers and 5% being gypsum. Gypsum is as an additive to increase the setting time of the cement to a workable 30 minutes or more.. OPC Cement gives high compressive strength at early ages and at 28 days. A 53 Grade cement gives up to 70 MPa strength against a minimum 53 MPa specified by BIS.

Portland Composite Cement (PCC) Crown Portland Composite Cement is CEM-II/A-M which is a cement consisting of Clinker, Gypsum, Pulverized Fuel Ash (PFA), Blast Furnance Slag and Limestone designated by the specifications of BDS EN 197-1: 2003; CEM -II/A-M (V-S-L), 42.5 N. PCC is the most suitable cement for constructions in Bangladesh.

Jan 01, 2019 The cement used was of uniform colour (grey with a light greenish shade), free from any hard lumps. Table-1 summarises the results of tests conducted on cement in accordance with procedure laid down in IS 8112: 1989 [8] Table-1: Physical properties of Grade 43 Portland cement. S. No.

The initial setting time of OPC is 30 minutes. The initial setting time of OPC is also 30 minutes. Final setting time of OPC cement is 280 minutes i.e. 11.67 days. The final setting time of PPC is 600 minutes i.e. 25 days. It has more final setting time. So, it helps to better finishing of concrete.

The setting time of the by the Vicat apparatus IS 4031 (Part 5) : 1988 following requirements: a) Initial setting time than 30, and cement, when tested method described in shall conform to the in minutes, not less b) Final setting time in minutes, not more than 600. 6.3.1 If cement exhibits false set, the ratio of

May 04, 2013 Initial setting time=t 2-t 1. Final setting time=t 3-t 1, Where, t 1 =Time at which water is first added to cement. t 2 =Time when needle fails to penetrate 5 mm to 7 mm from bottom of the mould. t 3 =Time when the needle makes an impression but the attachment fails to do so. Precautions. Release the initial and final setting time needles gently.
