Ordinary Portland Cement (OPC) Bosowa Cement is high quality portland cement that has met national standards, namely SNI 2049: 2015 and international standards namely ASTMC 150 / C150M-12 and European standards EN 197 -1 CEM I. Portland cement type I is a suitable type of cement for a wide variety of concrete applications where special requirements are not required.
For an average Portland cement concrete cured under normal temperature and moisture, Abrams gave the relationship between compressive strength and water/cement ratio as ; (4) f c 7 = 63.45 14 x and f c 28 = 96.55 8.2 x where, f c 7 and f c 28 are the strengths in MPa at 7 and 28 days, respectively. Moreover (x) is the water/cement ratio.

OPC and PPC Grade. As per the classification of Bureau of Indian Standards (BIS), OPC comes in three different grades, including 33 grade, 43 grade and 53 grade. Due to weak compressive strength, 33 grade is normally not opted where high grade of concrete viz, M-20 and above is required. 43 grade is widely used for its multiple applications.

(r) Concrete Sleeper grade Cement (s) High Alumina Cement Ordinary Portland Cement Ordinary Portland cement (OPC) is by far the most important type of cement. All the discussions that we have done in the previous chapter and most of the discussions that are going to be done in the coming chapters relate to OPC. Prior to 1987, there was only one
GRADE: C40 CONCRETE. Strength: 40 Newtons after 28 days. C40 is a strong grade of concrete that is mostly used on commercial construction sites, where it will be utilised to create foundations and beams for support and roads. C40 is also used in chemically harsh environments where the additional strength can combat and contain acidic and ...
The Standard deviation (S) value for the M30 grade concrete is given in table 8 of IS456. Table 1 Standard Deviation for M25 grade Concrete – IS10262 Codebook. After 28 days of curing in water, concrete should have more than 38.25 N/mm 2 of compressive strength when it is tested in the Direct Compressive Testing Machine (CTM).
decreased initial compressive and tensile strength compared to OPC concrete. However, by 14 days, the grade 120 slag cement concrete strength equaled or surpassed that of OPC concrete. Compared to OPC concrete, the time to reach 3000psi traffic opening strength was delayed by 1 to 2 days for 30% replacement and by 3 to 4 days for 50% replacement.
OPC cement is Ordinary Portland Cement and in general concrete construction when there is no exposure to sulfates in the soil or groundwater OPC is the most common cement which is used. For almost all structural work including all kinds of concrete construction, OPC is an ideal building material and is one of the most commonly and widely used ...
In this research work, M20 grade mix of concrete (with water - binder ratio as 0.48) is adopted with glass powder (GP) and Sugar Cane Bagasse Ash (SCBA) as partial replacement of cement. GP is an inert material, they occupy the landfill space for considerable amount of time unless there is a potential for recycling.
The grade depends on the relative mortar strength of slag-portland cement mortar relative to that of a reference Portland cement mortar. GGBS is thus classified as Grades …
1. Concrete Mix Design for M35 grade concrete with fly ash : Type of cement = OPC 43 grade, specific gravity = 3.15, slump = 100, Type of coarse aggregate = crushed angular aggregate 20 mm with specific gravity =2.74 Type of fine aggergate = zone -1-sand with specific gravity of 2.74, exposure severe. method of concreting = pumping.
The partial replacement of the siliceous aggregates with up to 20% of recycled concrete aggregates induced no change in mixing liquid uptake, in either AAM or OPC mortars. All the AAM and OPC ...
Each group of concrete mix with natural and manufactured sand consisted of five sub-groups, having 0%, 30%, 50%, 80% and of GBS content. Other pozzolanic materials such as fly ash and silica fume were also employed to replace ordinary Portland cement (OPC) at 20% and 8% respectively, with a constant w/c ratio of 0.32 for the desired slump ...
