• ### 2aConcrete Mix Design VTC

 It is generally accepted that the variation in concrete strengths or a particular mix follows the normal distribution as shown below:  In the figure above, the mean strength of the mix is 40 N/mm. 2. That is, we can expect half of the test results will be higher than 40 N/mm2 and half will be lower.

If the density of plain (unreinforced) concrete is 2400 kg/m3 and that of steel is 7850 kg/m3, calculate the unit weight  (in kN/m3 ) to three significant figures of reinforced concrete that contains the following volumes of steel. Take g = m/s2 . (a) % (typical slab) [Ans. kN/m3 ] .

• ### CIP 36 Structural Lightweight Concrete

Equilibrium density will be approximately 3 to 8 lb/ ft 3 (50 to 130 kg/m3) less than the fresh density and a correlation should be agreed upon prior to delivery of concrete. The tolerance for acceptance on fresh density is typically ±3 lb/ ft 3 (±50 kg/m ) from the target value.
