Cement

CHAPTER-1 INTRODUCTION Concrete a manmade material widely and greatly used in construction Industry. This concrete is a mixture of adequate proportion of cement, water and aggregate. Hardening (or) strength of this material is obtained by the chemical action between water and cement. As the time increases the stronger it grows (i.e strength of concrete is directly proportion to its age).The durability, strength, versatility and other characteristics of concrete depends upon the properties and…

A sand-cushioned system is cement based and is not bonded to the slab. It is wire-reinforced and is placed over a sand layer. A bonded system is cement based and is bonded to the slab. It is placed on the slab with a terrazzo topping. A polyacrylate system is cement-based, but modified with additives, and is bonded indirectly to the slab. The terrazzo is placed on top of a fixed membrane. An epoxy…

and compressive strength properties of the concrete produced by replac-ing 5%, 10% and 15% by weight of ordinary Portland cement with Sawdust Ash (SDA). Slump test was carried out on the fresh concrete and compressive strength test on hardened concrete. The concrete cubes were tested at the ages of 3, 7, 14 & 28 days. The results showed that Sawdust Ash is good with use in cement. The slump decreased as the Sawdust Ash content increased indicating that concrete becomes less workable as the…

On the site visit from 7th October there were many materials that were playing an important part in the development of the roadworks, including steel, concrete/cement and many more. Below I have selected three materials from the site visit and identified properties and uses. • Steel There are over 3000 different grades of steel all with unique physical and chemical properties. The production of steel is made in accordance with its application. Due to its high strength Steel is one of the most…

the ratio of cement to sand to gravel. Also the cost of making a concrete is significantly lower than the cost of making a material that will perform in the same way. Hard core This material must be bought in order to make sure it includes the right numbers of sand and stone, the usual amount would be around 20mm to dust, this will provide good help when compacted and will provide a good sold base for the layers above. Sub base…

3. MIX DESIGN 3.1 Design of Geopolymer Concrete Mixtures: In the mix design of geopolymer concrete the role and the influence of aggregates are considered to be the same as in the case of Portland cement concrete. The mass of combined aggregates may be taken to be between 75% and 80% of the mass of geopolymer concrete. Coarse and fine aggregate together were taken as 77% of entire mixture by mass. Fine aggregate was taken 30% of total aggregate. Fly ash and alkaline liquids was taken 23% of…

Hydroxyapatite (HA) has been studied for their excellent performances which are suitable for use in bone defects or regeneration of bone. Hydroxyapatite (HA) has poor mechanical properties which make it limited used in a load bearing area. In this case, sodium alginate (SA) was used to be mixed with hydroxyapatite (HA) by using precipitation method to increase the mechanical and physical properties. The mixing of hydroxyapatite/sodium alginate effectively increases the densification and hardness…
