Abstract:Strength tests were carried out on prepacked concrete and reinforced prepacked concrete beams and the results were compared with those obtained on normal concrete. Little difference was found in strength properties between pre-packed and normal concretes. It was also found that the pre-dicted flexural strengths of reinforced prepacked concrete based on either the straight-line theory or the ultimate strength theory were greater than those of normal concrete. Consequently, it is concluded that for practical purposes of designing reinforced flexural members the accepted formulas based on either the straight-line theory or the ultimate strength theory may be applied to prepacked concrete as well as to conventional normal concrete.
