Ancient construction techniques

The transport and use of unnecessarily large blocks of stone, the specific selectivity of stone type along with various examples of 'extreme' masonry at numerous sacred and ancient monuments is starting to reveal a reverence for stone itself, an idea which has foundation in mythology, religion and can still be seen today at Jerusalem, Mecca, the 'Lignum' of India and at the crowning of any new ...

Raw materials for cement manufacturing

Lime Component Limestone: Common forms of calcium carbonate used as raw material for cement manufacturing are limestone and chalk.Limestone is of predominantly fine grained crystalline structure, its hardness is between 1.8 to 3.0 of the Mohs scale of hardness and specific gravity 2. To 2.8. Limestone usually contains admixtures of clay substance or iron compounds, which influences its color.

How Aggregate Cement Ratio Affect Workability of Concrete ...

Oct 26, 2017  When the weight of cement is less, i.e. aggregate cement ratio is more, then there will be very less cement paste to coat aggregate surfaces and fill the voids, thus, mixing, placing and compacting of concrete will be more harder than previous case. This implies, the workability of concrete will be less than previous case.
