These properties include cement slurry rheological properties, free water, fluid loss, thickening time, cement stone elastic properties and compressive strength.
The goal of the experimental campaign was to evaluate the most important mechanical parameters needed for numerical modelling of traditional rubble stone masonry walls, namely, the compressive strength and Young's modulus through compression tests; the cohesion and friction coefficient by triplet tests; and the diagonal tensile strength via diagonal compression tests.
The stone's properties such as compressive strength, thermal conductivity, durability, impact resistance and water absorption were experimentally measured and compared with natural stone specimens.
Simultaneously to the application of NDT's were carried on destructive tests on the stone masonry, like compression tests, to obtain compressive strength, Young's modulus and Poisson's ratio.
In this work Ultrasonic Pulse Velocity (UPV), Schmidt Hammer Rebound (SHR) test and strength assessment on microcores (UCSm) and standard cubic samples (UCSc) were used to detect the uniaxial compressive strength of stone masonry units.
The results indicated that the compressive strength of cement stone significantly improved by colloidal nanosilica.
Influences of stone powder content on long-term compressive strength of concrete with different water-to-cement ratios were analyzed.
The compressive strength of cement stone rises slowly when cementing marine shallow section at low temperature, resulting in increased drilling cost and risk.
It would involve mechanisms that could lead to the propagation of fractures at a stress lower than the tensile or compressive strength of the stone and that are discussed below.
One of the models is based on the chain saw penetration index, and uses the uniaxial compressive strength of the stone, weight of the chain saw machine and useful cutting depth of the arm as predictor parameters.
