Introduction to Cement | PPT
5. TYPES OF CEMENT Ordinary Portland Cement (OPC): The most commonly used type of cement, which is a basic ingredient of concrete, mortar and most non-specialty grout. Rapid-Hardening Portland Cement (RHPC): These cements are more finely ground than OPC and strength gain ability is relatively faster than OPC.They also sets faster than OPC. Portland …
Ferrocement ppt | PPT
3. Mortar provides the mass and wire mesh imparts tensile strength and ductility. When building Ferro-cement structures the sand/cement mortar is applied to the reinforcing wire with a trowel, never poured like common concrete work. Often a form is used to provide the desired shape. Ferrocement is a super reinforced concrete. It differs from conventional …
BUILDING MATERIALS & CONSTRUCTION UNIT -1 LECTURE SERIES: CEMENT
INTRODUCTION Cement is a commonly used binding material in the construction. Cement is obtained by burning a mixture of calcareous (calcium) and argillaceous (clay) material at a very high temperature then grinding the clinker so produced to a fine powder.
Soil Cement Seminar ppt
Soil-cement is a highly compacted mixture of soil/aggregate, portland cement, and water. Soil-cement differs from Portland cement concrete pavements in several respects. One significant difference is the manner in which the aggregates or soil particles are held together.

Ferrocement | PPT
Ferrocement is a type of thin reinforced concrete made of cement mortar reinforced with closely spaced wire mesh. It has a higher ratio of steel to cement than conventional concrete. Ferrocement was invented in France in the 1840s and provides high tensile strength, durability, and versatility due to its composition and thin walls.

CEMENT.
Cement is obtained by burning together, in a definite proportion, a mixture of naturally occurring calcareous (containing calcium carbonate or lime) and argillaceous (containing alumina) material to be partial fusion at high temperature about 1450 c.
CEMENT.
Concrete is a composite material consisting of aggregate (gravel and sand), cement, and water. As a construction material, concrete can be cast in almost any shape desired, and once hardened, can become a structural (load bearing) …

seminar topic on high density concrete- | PPT
4. COMPOSITION For producing high density concrete it uses heavy natural aggregates such as barites or magnetite or manufactured aggregates such as iron or lead shot The density achieved will depend on type of aggregate used typically using barites the density will be in the range of 3500kg/m³ (45% greater), while with magnetite the density will be …

Self Healing Concrete | PPT
4. DEFINITION – Self healing concrete is a concrete which heals itself when it comes in contact with air and water, it produces lime on outer layer of concrete. * In most of the traditional concrete mixtures 20-30% of the cement is left unhydrated. * If cracking of the concrete occurs, unreacted cement grains may become exposed to moisture penetrating the crack.
Soil Cement in Construction Seminar ppt
Soil cement is frequently used as a construction material for pipe bedding, slope protection, and road construction as a sub base layer reinforcing and protecting the sub grade. It has good compressive and shear strength, but is brittle and has low tensile strength, so it is prone to forming cracks.

High strength concrete | PPT
It defines HSC as concrete with a 28-day compressive strength of over 40 MPa. HSC uses a low water-cement ratio, smaller aggregate sizes, and admixtures like silica fume and superplasticizers. Compared to normal-strength concrete, HSC has higher resistance to pressure, modulus of elasticity, and strength gained at an earlier age.

CEMENT.
Concrete is a composite material consisting of aggregate (gravel and sand), cement, and water. As a construction material, concrete can be cast in almost any shape desired, and once hardened, can become a structural (load bearing) element. Portland cement may be grey or white. Function Mass % Calcium oxide, CaO Controls strength & soundness.
