a research program was conducted on different clay-bearing rocks selected from the ilam, sarpol-e zahab and tajarak regions (iran) to predict their slaking characteristics. the new durability apparatus (nested mesh drums) separates disintegrated particles varying from > 25.4 to < 2 mm as the drums were rotated. on the basis of the particle size distribution, the disintegration ratio (dr) was us...

Current advances in timber engineering with the use of at longer spans necessitate high performance joints. Glued-in rods exhibit axial load capacity and stiffness are suitable for such applications. FRP can increase their durability fire but ways to produce progressive failure mechanisms necessary enhance resilience. In this study CFRP GFRP glued block laminated epoxy investigated under both m...

An epoxy-coated reinforcement geopolymer concrete structure with good durability and energy-saving properties can be formed by combining concrete. The bond strength is the precondition for two to work together. In this paper, 13 beam specimens (11 reinforcements 2 ordinary deformed reinforcements) were designed investigate influence of concrete, diameter reinforcement, bonding length type on pe...

Natural plant fibers represent a sustainable alternative to conventional fiber reinforcement materials in cementitious due their suitable mechanical properties, cost-effective availability and principle carbon neutrality. Due its high tensile strength stiffness as well worldwide distribution along with rapid growth, bamboo offers itself particular source. In experimental studies on concrete bea...

Historical masonry structures made from locally available materials such as stone, brick, and mud are an integral part of our cultural identity. Moisture content is a critical environmental factor that can significantly impact the durability strength these structures. ingress in cause detrimental effects decreased strength, increased porosity, reduced bond between mortar units. Understanding th...

As one of the ways contributing to progress industrialization construction industry, 3D printed concrete (3DPC) has attracted more and attention in recent years. The utilization 3DPC can accelerate speed, save labor raw materials, as well improve design freedom without formworks. However, most significant challenges for application is printing materials. These a difference mixtures performance ...
