一、水灰比是算出来的吗读本刊1984年第1期“鲍罗米公式小议”,文中杨煜惠同志评论经验系数A、B值时写道:“公式本来就只能做大概的推算之用……全国统用一个系数未尝不可。”这一观点笔者基本同意。由此联想到目前有关混凝土配合比设计工作,在认识和实践上有些问题还值得讨论一下,这里愿意申述一下个人看法,也许对于今后工作不无裨益。鲍罗米公式中的经验系数自解放初期引进A=0.55(碎石混凝土)或0.50(卵 First, the water-cement ratio is calculated? Read this volume in 1984, “Balomi formula formula”, in the article Yang Yihui commented on the empirical coefficient A, B value, wrote: "The formula can only do about The use of projections... It is a good idea to use a single coefficient throughout the country.” The author generally agrees with this view. From this, it is thought that there are some problems related to the concrete mix design work. It is worthwhile to discuss some problems in the understanding and practice. It is willing to express personal opinions here, and may be useful for the future work. The empirical coefficient in the Borrome formula was introduced from the early days of liberation with A = 0.55 (gravel concrete) or 0.50 (egg
