Special functions of concrete:It is used in building residential houses, apartments,etc.,It is used in precast elements.It is used in underwater constructionIt is used to construct infrastructures.
The raw material used for manufacture of cement are limestone and clay. They are ground to form very fine powder and then converted to slurry. The slurry is baked at very high temperature to form granular mass called kilnker. The kilnker is ground and mixed with powdered gypsum to form cement.
As sand is a course granular substances binding agents such as cement and lime can grip to the sand and form stronger bonds - if the mix was all powdery like a cement it would be more line a slurry or even a doh like consistency which would not hold very well under pressure and in weathering. When buildings were first created using mud (wattle and daub) course materials were put in the mix like animal hair and even manure to brake up the slurry like consistency and add strength to the mixure
Cement paste is formed when cement is mixed with water. However, cement mortar is formed when cement is mixed with fine aggregate (sand) and water.The strength of cement mortar is more when compared to cement paste.Shrinkage will be less in cement mortar and high in cement paste.
The level of suspended solids in cement slurry can vary, but it typically ranges from 20% to 40% by volume. The amount of suspended solids can be influenced by factors such as the type of cement used, the mixing procedure, and any additives or admixtures included in the slurry. Testing and monitoring the level of suspended solids is important to ensure the desired consistency and performance of the cement slurry.
cement grouting is the process of injecting the cement slurry in to the engineering structures to stabilize the structure.
How can cement slurry modefy to enhance its function in oil well cementing operation?

you have to remove paint n rough the surface then put some cement slurry n paste the tile by cement
As of June 2014, the price for cement slurry is around $180 per yard. This includes delivery. Most places offer a quantity discount. For instance, the current price if you order 6 or more yards is around $88 per yard.
If you are installing on a concrete slab, then make a sand bed with sand & cement mixed to a praportion of 1:25. Level the bed. Then make cement slurry by mixing water. Pour the slurry on the bed for about an area slightly bigger than tile. Place the water soaked tile & give light blows by a wooden piece. then repeat the same procedure for next tile. Next day clean the joints & remove all excess cement slurry which has come out. Rake the joints. Then fill the joints by slurry of white cement. After a drying period of 2 hours, remove the excess white cement slurry. Pour some water for three days to keep the joints wet. If you want to install on prelaid flooring tile, then first grind the existing tile surface to make it rough. Then make cement slurry with polymer additive. Then paste the tiles on this rough surface by applying 3 to 4mm of layer of slurry. Sanjay - nikiasso@yahoo.com

when concrete is vibrated while pouring in to the form work, the cement slurry part tends to get drained through voids between aggregates and the richest part of cement slurry is detained at bottom portion of column. this causes a strong, dense, and void free concrete which ensures better compressive strength than the concrete on top portion of column.
Papercrete is made from a slurry of mashed newspaper, Portland Cement, a little Borax (to prevent mold), and water. Some people add sifted dirt or straw.
You use a slurry mixture of lime and cement mixed with sand and small gravel. Throw this mixture at the wall with a trowel or scoop and add stones or pebbles on top.
