Rapid Hardening Portland Cement (RHPC) Rapid hardening cement is similar to Ordinary Portland cement but with higher tri-calcium silicate (C3S) content and finer grinding. It gains strength more quickly than OPC, though the final strength is only slightly higher. This type of cement is also called as High-Early Strength Portland Cement. The one-day strength of(…)
Building materials provides information on various modern construction materials that are used these days. It also gives information about aggregates, cement, bricks, woods, reinforcement, light weight aggregates, recycled aggregates and other modern materials used in construction industry.
Cement is defined as the product manufactured by burning and crushing to powder an intimate and well-proportioned mixture of calcareous and argillaceous materials. The cement, which is generally used for preparing concrete, is the Ordinary Portland Cement. But for special purposes other qualities of cement such as Low Heat Cement, Rapid Hardening Cement, High Alumina(…)
Effect of Fire and High Temperature on FRPs The use of externally-bonded FRP plates and sheets to strengthen existing reinforced concrete structures is now widely recognized. However, a primary concern that still discourages the use of FRPs in some cases is their assumed susceptibility to fire. While recent studies have demonstrated that the overall performance(…)
Mechanical Properties of FRPs Many FRPs have tensile strengths that exceed the strength of steel, but their stiffness is generally lower than that of steel. When loaded along the fiber direction they behave essentially linearly until fracture, and are therefore brittle by nature. Stress Corrosion and Stress Rupture The average ultimate tensile strength of freshly(…)
Following table shows the properties components, properties and applications of common wall materials such as various types of bricks, partition boards etc. Wall Materials Composition Properties Applications Fired Common Bricks (including clay bricks,-fly ash bricks, shale bricks, and coal gangue bricks ) Made by sintering the clay materials Compressive strength: 10-30MPa; apparent density: 1500-1800kg/m3;(…)
Advanced Composite Materials (ACMs) can be defined as combination of materials appropriately arranged using reinforcing fibers, carefully chosen matrixes, and some times auxiliary materials like adhesive core and other inserts. These combinations after proper manipulation and processing result in finished structure/item with synergistic properties i.e. properties achieved after fabrication cannot be obtained by individual components(…)
Knowing Green Building materials is an important step in designing a green building to be more efficient and energy saver. Green Building Materials list is presented here.
Three Phases of Building materials: A material’s life cycle can be organized into three phases: Pre-Building Building; and Post-Building. These three life-cycle phases relate to the flow of materials through the life of the building. The evaluation of building materials’ environmental impact at each stage allows for a cost-benefit analysis over the lifetime of a(…)
