Freeze–thaw Resistance of Concrete Based on Fly Ash and Municipal Sludge Under Alkali Excitation

工程科学与技术
In this study, municipal sludge modified with quicklime is employed to replace 10% of the fine aggregate, while fly ash replaced 10%, 20%, and 30% of the cement to mitigate the adverse effects of municipal sludge on the freeze–thaw resistance of concrete.

Analysis of the static and dynamic elastic moduli of a one-coat rendering mortar with laboratory and in situ samples

Case Studies in Construction Materials
Although the compressive strength is the most commonly used property to characterize mortars, it has limited representativeness in real-world applications.

Determination of Dynamic Modulus of Elasticity of Concrete by Impact Hammer

HDKBR INFO Magazin, 2016
Experimental determination of dynamic modulus of elasticity of fiber-reinforced concrete (FRC) by using impact hammer is based on measuring resonant frequencies of flexural vibrations in prismatic specimens. The natural frequencies are determined as resonant peaks from frequency response function (FRF), which is obtained by measuring the excitation and
