本文研究了利用约旦东北部的天然凝灰岩作骨料生产高强轻质砼的可能性。用标准的试验方法,根据不同砼配合比的试验结果,获得了高质量的轻质砼。九十天的抗压强度高达60MPa。为了研究这类高强砼的短期力学性能,对不同形状和尺寸的大量试件在不同龄期下进行了试验。所得到的性能包括容重、泊松比、静弹性模量、试件形状和尺寸的影响、抗压强度随龄期的变化以及不同养护条件下的劈拉强度和断裂模数。
This article examines the possibility of producing high-strength, lightweight plutonium using natural tuffs from northeastern Jordan as aggregate. Standard test methods were used to obtain high-quality, lightweight crucibles based on the test results of different crucible mix ratios. Ninety days of compressive strength up to 60MPa. In order to study the short-term mechanical properties of such high-strength crucibles, a large number of test pieces of different shapes and sizes were tested at different ages. The properties obtained include bulk density, Poisson’s ratio, static modulus of elasticity, influence of shape and size of the test piece, variation of compressive strength with age, and tensile strength and modulus of rupture under different curing conditions.
