A binder is a substance that holds or binds other materials together. Two types of binding materials are hydraulic binders (e.g. cement) and non-hydraulic binders (e.g. lime). The difference lies in their ability to set and harden in the presence of water.

<p>Reinforced concrete is concrete in which steel reinforcement is embedded. Its advantages over plain concrete include increased tensile strength, improved resistance to cracking, and enhanced durability.</p> Signup and view all the answers

<p>The most important property of hardened concrete is compressive strength, while workability is crucial for fresh/liquid concrete. Compressive strength is crucial for structural integrity, and workability affects the ease of handling and placing concrete. Cubes, cylinders, and prisms are allowed shapes for mechanical tests. Hazards to the durability of concrete include chemical attack, freeze-thaw cycles, abrasion, alkali-aggregate reaction, and corrosion of reinforcement.</p> Signup and view all the answers

<p>The purpose of concrete cover is to protect the reinforcing steel from corrosion and fire, and factors considered for its design include environmental conditions, exposure to aggressive substances, and structural requirements.</p> Signup and view all the answers

<p>A partition wall is a non-load-bearing wall that divides the interior space, while a load-bearing wall supports the structure's vertical loads.</p> Signup and view all the answers

<p>A curtain wall is an exterior wall that does not support the load of the building. The functions of a roof include protection from weather, insulation, and supporting equipment. Four types of roof shapes are gable, hip, mansard, and flat.</p> Signup and view all the answers

<p>Three types of insulation used in civil engineering are thermal insulation, acoustic insulation, and moisture insulation. Possible causes of problems with moisture in buildings include leaks, condensation, and inadequate ventilation.</p> Signup and view all the answers

<p>Obligatory thermal insulation is provided to reduce heat transfer, improve energy efficiency, and maintain indoor comfort. Thermal bridging occurs when a conductive material creates a path for heat flow through an insulated assembly, for example, metal studs in a wall assembly.</p> Signup and view all the answers
