日本 Sharp 公司生产的 PC—1500袖珍电子计算机具有体积小,重量轻、携带方便、价格较低等优点。用以计算混凝土施工配合比其功能与内存量均能满足要求,易于推广。本文介绍用 PC-1500袖珍电子计算机计算混凝土施工配合比的程序设计。一,计算程序的功能1.能用体积法或重量法计算不同情况的混凝土配合比(如混凝土采用碎石或卵石、掺外加剂等)。能按最大水灰比和最小水泥用量的要求复核并修正
The PC-1500 portable electronic computer manufactured by Japan’s Sharp Company has the advantages of small size, light weight, easy to carry, and low price. It can be easily used to calculate the mix construction ratio of concrete construction and its function and memory capacity can meet the requirements. This article describes the use of PC-1500 pocket computer to calculate the concrete construction mix design. First, the function of the calculation program 1. Volumetric or gravimetric method can be used to calculate the concrete mix ratio of different conditions (such as concrete using gravel or pebbles, admixtures, etc.). Can review and amend according to maximum water-cement ratio and minimum cement requirement
