本文研究了以粉煤灰或磨细矿渣为唯一胶凝材料的碱激发硅酸盐无水泥混凝土的抗拉强度、弹性模量、泊松比和应力-应变关系。碱活性混凝土被证明是更强的张力和具有较低的泊松比波特兰水泥混凝土。提出的关系，以估计的抗拉强度和弹性模量的基础上的抗压强度的碱活性混凝土，这是目前所采用的波特兰水泥混凝土相同的形式。
This paper presents an investigation into the tensile strength, modulus of elasticity, Poisson’s ratio, and stress–strain relationships of alkali-activated portland-cement-free concrete made with fly ash or ground granulated blast furnace slag (GGBFS) as the sole binder. Alkali-activated concrete is shown to be stronger in tension and have lower Poisson’s ratio than portland cement concrete. Relationships are proposed to estimate the tensile strength and modulus of elasticity based on the compressive strength of alkali-activated concrete, which are of the same form as those currently employed for portland cement concrete.
