The most common cement used in the making of modern concrete is Portland cement. Portland cement was first produced in 1824 by a British stonemason, Joseph Aspdin. He heated a mixture of finely ground limestone and clay in his kitchen stove and then ground the mixture into a powder that hardened with the addition of water.

Cement slab cost. So how much does it cost to pour a concrete slab? In our area, hiring a concrete contractor to pour a 16 x 20-ft. slab like this one would cost ,000 to ,000. The amount of money you’ll save on a concrete slab cost by doing the work yourself depends mostly on whether you have to hire an excavator.
For design mix concrete water content is calculated from Wate/Cement ratio which depends on various factors like the weight of cement, workability etc. But for nominal mix concrete IS456 codebook suggests the following quantities per bag of cement.
Structure factor calculations for cementite; The name. The name has its origins in the theory of Osmond and Werth, in which the structure of solidified steel consists of a kind of cellular tissue, the iron constituting the nucleus and the carbide the envelope of the cells. The carbide was therefore envisioned to cement the iron.
The exceptional durability of portland cement concrete is a major reason why it is the world’s most widely used construction material. But material limitations, design and construction practices, and severe exposure conditions can cause concrete to deteriorate, which may result in aesthetic, functional, or structural problems.

The simplest – and strongest – form of anchor bolt is cast-in-place, with its embedded end consisting of a standard hexagonal head bolt and washer, 90-bend, or some sort of forged or welded flange (see also Stud welding). The last are used in concrete-steel composite structures as shear connectors.
To keep the patio from being invaded by weeds, use commercial-grade landscape fabric (Image 1). The addition of this material is vital for three reasons: to keep weeds from growing up through the pavers, to prevent the pavers from sagging and becoming uneven and to reinforce the area beneath the pavers with its built-in layer of sand and gravel while still allowing water to flow through the ...
