Concrete mixing ratio by volume used cement: sand: stone 1:2: 4, or Mixed water mixing ratio Desing by simen (Water Ratio) is between 0.50-0.60 to pralai test of strengths at 28 days of age the compressor pralai. Not less than 240 kg per square cm. Strengths of concrete pralai fc ' = 240 kg/sq cm. The unit accepts, of concrete fc = 0.375 xfc ' bar = 90 kg/sq. cm.The unit shear beam (Beam), Vc1 = 0.29 xSqr (fc) = 4.49 kg/sq. cm.A tight unit shear (Punching Shear), Vc2 = 0.53 xSqr (fc) = 8.21 kg/sq. cm.The unit shear from torque torque (Mt) Vc3 = 1.32 (fc) = xSqr kg/sq. cm, 20.44.Elastic modulus of concrete (fc) EC = 15210xSqr = kg/sq. cm 235,632.Steel Fy = 2400 kg/sq. cm. Fs = 0.5 * fy = 1200 kg/sq. cm. Es = 2,040,000 kg/sq. cm.Steel deals Fy = 2400 kg/Oi sq. cm. Fs = 0.5 * fy = 1200 kg/sq. cm. Es = 2,040,000 kg/sq. cm.Iron and steel, according to the market.Is the point of a steel Fy = 2400 kg/sq. cm. The unit tensile strength that allows (AISC) Ft = 0.60 kg/sq. cm. xfy. Ft = 1386 kg/sq. cm.The unit tensile strength that allows (AISC) Fb = 0.60 kg/sq. cm. xfy. Fb = 1386 kg/sq. cm.The strength of the steel allowed the unit. Line, circle, and sugarcane N = Es/Ec = 8.65 K = 1/[1+(fs/n*fc)] = 0.355 SR24 2/4
