Concrete for the construction is heavy, and the class of longitudinal reinforcement is A400C. The following parameters were variable: the percentage of reinforcement,classes of ρ heavy concrete,and the ratio between the areas of reinforcement (relevant for sections with double . C reinforcement).
The test parameters included crosssectional shapes, crosssectional diameters/widths and stirrup ratios. The test results indicated that both the circular and square BFRP reinforced concrete (RC) columns presented a notable size effect on nominal compressive strength and ductility. As the crosssectional size varied from 200 mm to 600 mm, theWeb crushing strength of reinforced and prestressed ,The web crushing strengths of 16 reinforced and prestressed concrete Ibeams are reported. The principal variables of the test specimens are the ratio of yield force in the prestressed steel to yield force in the nonprestressed steel and the area of vertical stirrups. The test strengths are compared with the upper limit on shear strength given by ACI Building Influence of the number of cores on concrete strength ,Reinforced concrete (RC) is used in most constructions (e.g., buildings, bridges, tunnels, and dams) due to its high strength and durability. However, over the years, old RC structures can be weakened under the permanent exposure to aggressive environmental conditions and different deterioration factors which affect their structural
2.3 Water/cement ratio. The water/cement (w/c) ratio during mixing is a crucial determinant of the strength of the cured concrete. A high w/c ratio results in a lowviscosity mix that is generally easier to pour. Such a mix would be referred to as being more workable.

The research included a variety of blends of steel and polypropylene fibres, each with a volume percentage of 1 %: 0 %, 0 %, 25 %, 50 %, 75 %, and 100 %. Specific gravity of
Compressive Strength of Concrete at 7 Days. Concrete has the ability to gain 16 percent strength of its total strength in one day, 40 percent in 3 days, 65% in 7 days, 90% in 14 days, and around 99% strength in 28 days. So, for the M20 grade of concrete compressive strength of concrete during the day will be 13 N/mm2.Concrete Pipe Design CivilWeb ,The concrete pipe crushing strength is not the only factor affecting the strength of the overall concrete pipe system. The bedding type has a significant impact as it What Is Crushing Strength Of Reinforced Concrete Ratio,Cement + Coarse Aggregate + Fine Aggregate + water The quality of concrete depends on the mixproportions, types of cement, cement/water ratio The concrete strength is measured by crushing strength (compressive test) of cubes or cylinder Concrete of a given strength is identified by its 'class' Class 25/30; where cylinder crushing strength is 25N/mm2 and
