Yes it can be substituted with lime mortar. Slaked lime mortars have been used for thousands of years whereas the use of cement in construction is relatively recent. The vast majority of buildings in this country dating pre 1910 would have been made using lime mortar to lay the bricks, render the outside and plaster …
Portland cement is similar to ordinary, gray Portland cement in all aspects except for its high degree of whiteness. Obtaining this color requires substantial modification to the method of manufacture, and because of this, it is somewhat more expensive than the gray product. Chemical composition of white cement:- Uses:- For joining marbles and ceramic tiles . For preparing …
Wet process There are two different processes of manufacturing cement. wet process minerals are wet ground (by adding water) to form a slurry and then dried, dry process minerals are dry ground to form a powder like substance.Both the processes are in use and have their own advantages and disadvantages.While in wet process grinding is …

And he called it that because the color resembled the stone that they quarried on the Isle of Portland off the British coast. Now, his method involved the careful proportioning of …
WHAT IS FINENESS OF CEMENT? Fineness of cement is property of cement that indicate particle size of cement and specific surface area. and indirectly effect heat of hydration. IMPORTANCE/EFFECT OF FINENESS OF CEMENT: Fineness of cement affects hydration rate hence the rate of strength gain. The smaller the particle size, the greater the surface area-to-volume …
