Abstract:
Mass concrete need not necessarily contain aggregate, 3 and 6 in. (76 and 152 mm) nominal maximum size. However, measures must be taken if temperature-related cracking is to be avoided. Section and Proportioning of ingredients will have significant bearing on the heat generated within any as crete and on the potential for temperature cracking as the thickness and dimensions of the work increase. Therefore, the most favorable mixture for masr concrete work will incorporate use of the follow available cements with the lowest possible heat of hydration; pozzolans and chemical admixtures; clean, well-graded coarse aggregate of the largest practical size; the minimum quantity of fine aggregate; and
