![]() ![]() Cement should have grey color with light greenish shade. Quality of cement can be checked with color, physical properties, etc. What field tests are required for quality check of cement? ![]() It is usually formed during concrete casting.ġ5. Honeycomb, also known as air pocket, is nothing but the air voids in concrete. What do you mean by honeycomb in concrete? How many hours should CBR samples be soaked ?īearing capacity is the capacity of soil to support the loads applied to the ground by the foundation of the structure.ġ4. What is the minimum weight of fine aggregate for sieve analysis as per ASTM C136 ?ġ2. It also recommends that the curing duration should not be less than 10 days for concrete of OPC exposed to dry and hot weather conditions and 14 days for concrete with mineral admixtures in hot and dry weather.ġ1. IS 456 – 2000 recommends that curing duration of concrete must be at least 7 days in case of Ordinary Portland Cement, at least 10 days for concrete with Mineral admixtures. A wall constructed to resist the pressure of an earth filling, is known as What is the process of covering of concrete placed on the exposed top of an external wall ?ĩ. For filling cracks in masonry structures, the type of bitumen used, isĨ. Axial force is the force in the beam acting parallel to the longitudinal axis.ħ. For design purposes, the beam’s ability to resist shear force is more important than its ability to resist an axial force. Shear force is the force in the beam acting perpendicular to its longitudinal (x) axis. The most common or simplest structural element subjected to bending moments is the beam. What is the bending moment (BM) & Shear force (SF) – Explain.Ī bending moment is the reaction induced in a structural element when an external force or moment is applied to the element causing the element to bend. For filling cracks in masonry structures, the type of bitumen used, isĦ. It is a highly effective process for repairing concrete walls or damaged surfaces.ĥ. It is a process in which mixture of cement & sand in proportion of 1:3 is shooted on concrete surface with the help of cement gun under pressure of 2 to 3 kg/cm 2. Basic knowledge of computer and architect related software programs.Conceptual understanding of designing models.what are the skills required to become an architect ? What is the maximum allowable fresh concrete temperature until used as per ASTM ?ģ. Strength of concrete cube of 150mmX150mmX150 mm tested at the end of 28 days should be minimum 25 N/Sq.mmĢ. What Do You Understand by M25 Concrete?Īccording to IS 456 : 2000, M refers Mix and 25 refers the characteristic compressive.
