This method of concrete cutting known as "flat sawing" is regarded as the most highly utilised diamond cutting method. It is generally used in the cutting of horizontal flat surfaces, such as flooring, pavement and bridge decks. Flat saws (slab saws) have a diamond blade mounted on a mobile machine that requires only one operator.
The Tunstead site is home to one of the largest limestone quarries in Europe, producing over six million tonnes of stone a year. The process is highly efficient as the extraction of limestone, production of lime and cement are all intrinsically linked and over 99% of quarried material is converted into saleable products and the remainder is used on site for restoration purposes.

Role of Concrete Curing. Curing plays an important role on strength development and durability of concrete. Curing takes place immediately after concrete placing and finishing, and involves maintenance of desired moisture and temperature conditions, both at depth and near the surface, for extended periods of time.
Vertical displacement: Cracks which are caused by soil settlement or heaving typically exhibit vertical displacement of the concrete; concrete on one side of the crack will be higher than concrete on the other side. Linear crack continuity: Cracks caused by shrinkage are typically not linearly continuous.
Cement kilns are used for the pyroprocessing stage of manufacture of portland and other types of hydraulic cement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates.Over a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant.
