How to Lay a Block Wall with Cement or Cinder Blocks

A structure is made from concrete containing Type I cement. The average ambient relative humidity is 70 percent. The concrete was moist-cured for 7 days. fc^'=4000 psi. (a) Compute the unrestrained shrinkage strain of a rectangular beam with cross-sectional dimensions 8 in. ×20 in. at 2 years after the concrete was placed. (b) Compute the stress-dependent strain in the concrete in a 20 in . ×20 in . ×12 ft plain concrete column at age 3 years. A compression load of 400 kips was applied to the co
