About Cement , types and uses

A cement is a binder, a substance used in construction that sets, hardens and adheres to other materials, binding them together. Cement is seldom used solely, but is used to bind sand and gravel (aggregate) together. Cement is used with fine aggregate to produce mortar for masonry, or with sand and gravel aggregates to produce concrete

 The following are the types of cement that are in practice:


  • Rapid Hardening Cement
  • Quick setting cement
  • Low Heat Cement
  • Sulphates resisting cement
  • Blast Furnace Slag Cement
  • High Alumina Cement
  • White Cement
  • Coloured cement
  • Pozzolanic Cement
  • Air Entraining Cement
  • Hydrographic cement


Types of Cement and uses

Rapid Hardening Cement

Composition : Increased Lime content

 Purpose :  Attains high strength in early days it is used in concrete where formworks are removed at an early stage.

Quick setting cement

 Composition: Small percentage of aluminum sulphate as an accelerator and reducing percentage of Gypsum with fine grinding

 Purpose :Used in works is to be completed in very short period and concreting in static and running water

Low Heat Cement

 Composition:  Manufactured by reducing tricalcium aluminate

Puprpose: It is used in massive concrete construction like gravity dams

Sulphates resisting Cement

 Composition:  It is prepared by maintaining the percentage of tricalcium aluminate below 6% which increases power against sulphates

Purpose : It is used in construction exposed to severe sulphate action by water and soil in places like canals linings, culverts, retaining walls, siphons etc.,

Blast Furnace Slag Cement

Composition: It is obtained by grinding the clinkers with about 60% slag and resembles more or less in properties of Portland cement

Purpose :It can be used for works economic considerations is predominant.

High Alumina Cement

Composition:  It is obtained by melting mixture of bauxite and lime and grinding with the clinker it is rapid hardening cement with initial and final setting time of about 3.5 and 5 hours respectively

 Purpose :It is used in works where concrete is subjected to high temperatures, frost, and acidic action.

White Cement

Composition: It is prepared from raw materials free from Iron oxide.

Purpose :It is costlier and is used for architectural purposes such as precast curtain wall and facing panels, terrazzo surface etc.,

Colored cement

Composition:It is produced by mixing mineral pigments with ordinary cement

 Purpose :They are widely used for decorative works in floors

Pozzolanic Cement

Composition: It is prepared by grinding pozzolanic clinker with Portland cement.

  Purpose :It is used in marine structures, sewage works, sewage works and for laying concrete under water such as bridges, piers, dams etc.,

Air Entraining Cement

Composition:  is produced by adding indigenous air entraining agents such as resins, glues, sodium salts of Sulphates etc. during the grinding of clinker.

Purpose:This type of cement is especially suited to improve the workability with smaller water cement ratio and to improve frost resistance of concrete.

Hydrographic cement

Composition : It is prepared by mixing water repelling chemicals

Purpose:This cement has high workability and strength

Hardy slab and where it use

  HARDY SLAB :- These kind of slabs are generally seen in Dubai and China. This  slab is constructed by hardy Bricks. Hardy bricks are hollow bricks and made up of concrete Hollow blocks are used to fill portions of the slab thickness it saves the  amount of concrete and hence the own weight of the slab is reduced. This kind of slab has a more thickness when compared with the conventional one. The thickness of hardy slab is 0.27m. The method of installing Hardy slab is different from normal  and it is clearly explained below: This is a one of the types of concrete slabs. The dimensions of Hardy brick is 40cm x 20cm x 20cm The process of execution is as follows: Step 1   : Formwork is arranged and then shutters are fixed on the formwork. Step 2  : Hardy blocks are placed on the shutter with one brick gap on the entire shutter. Step 3  : The gaps between the bricks are called as rib. Reinforcement is provided in a form of beam within the gap. Step 4  : After placing the

About Dome,Pitch roof,Arches slab

Dome Slab:- These kind of slab is generally constructed in temples, Mosques, palaces etc. And Dome slab is built on conventional slab. Thickness of Dome slab is 0.15m. Domes are in semi circle and shuttering is done on conventional slab in dome shape and concrete is filled in shuttering forming dome shapes. This is a one of the types of concrete slabs. PITCH ROOF SLAB: Pitch roof is an inclined slab , generally constructed on resorts for a natural look. Compared to traditional roofing materials Tile-sheets used in pitch roof slab  are extreamely lightweight. This weight saving reduces the timber or steel structural requirements resulting in significant cost savings.Tile-sheets are tailor made for each project offering labour cost savings and reduced site wastage. And the thickness of slab is depends on the tiles we using it may be 2″-8″. This is a one of the types of concrete slabs. Advantages : 1. It sheds off rain water better. 2. It gives you internal storage or ro

About slump cone test in concrete

Concrete Slump Test for Workability -Procedure and Results. Concrete slump test is to determine the workability or consistency of concrete mix prepared at the laboratory or the construction site during the progress of the work. Procedure for Concrete Slump Test: Clean the internal surface of the mould and apply oil. Place the mould on a smooth horizontal non- porous base plate. Fill the mould with the prepared concrete mix in 4 approximately equal layers. Tamp each layer with 25 strokes of the rounded end of the tamping rod in a uniform manner over the cross section of the mould. For the subsequent layers, the tamping should penetrate into the underlying layer. Remove the excess concrete and level the surface with a trowel. Clean away the mortar or water leaked out between the mould and the base plate. Raise the mould from the concrete immediately and slowly in vertical direction. Measure the slump as the difference between the height of the mould and that of height poin
