  • Miix Used For Different works

    The process of selecting the respective proportions of cement, sand, coarse aggregate and water to obtain concrete of desired quality is called concrete proportioning. There are various methods to determine the volume ratio of different components, such as arbitrary method, finesse modulus method, minimum voids method and maximum density method. Recommended concrete mixes for various…

  • Concrete Ingridients & their functions

    Cement concrete is an admixture composed primarily of relatively inert mineral matter held together in the form of particles or flakes by a binding medium, which gives concrete its strength and durability. Sand and stone chips or stone are the inert materials and a combination of portland cement and water is the binder. Inert material,…

  • Intro to Concrete

    Cement concrete is a synthetic construction material obtained by mixing cement, water and some other inert materials. In the plastic state, the mixture becomes hard as rock when allowed to set. By properly adjusting the proportions of the various ingredients, concrete with sufficient compressive strength for various uses can be produced. The strength of concrete…

  • Principles in bricks Masonry

    Lay the bricks on their bed with the frogs facing up.Courses should be truly horizontal and truly vertical joints.The use of bricks should be avoided as much as possible.Generally, the height of brick masonry is limited to 1.5 meters in a day.To ensure continuous bonding, the walls should be butted with a toothed end at…

  • Chamfered Ashlar 

    In this type of ashlar masonry, the strip is provided as above. However, it is chamfered or beveled at an angle of 45 degrees by a chisel to a depth of about 25 mm. Another strip 12 mm wide is then provided on the remaining exposed face of the stone and the surface inside the…

  • Rock or quarry faced Ashlar 

    In this case, the exposed faces of the facing stones between the chisel draftings all around are left undressed. However, the projections of sizes more than 8 cm are broken. All other specifications regarding the sizes of the stones and the bond are kept similar to that of ashlar rough tooled masonry .

  • Rough tooled Ashlar 

    Exposed faces of this type of masonry should be given a finely dressed chisel draft of about 25mm width. Between drafts, parts should be roughly tooled. Joint thickness should be 6 mm.

  • Masonry Ashlar fine

    In all beds, joints and face stones should be well prepared so that they conform to the desired pattern. Stones placed in regular courses should not be less than 300mm in height. The width of the stones should not be less than the height of the course. Also, the length of the stones should be…

  • Masonry ashlar

    It is expensive, high grade and high quality masonry. It is made of precisely dressed stones with uniform and very fine joints of about 3 mm thickness. By arranging stone blocks in different patterns, a variety of appearances can be achieved. Ashlar masonry walls can be backed with ashlar or rubble masonry.

  • Rubble masonry flint

    In this type of masonry, the stones used as flints are irregularly shaped nodules of silica. Width and thickness vary from 80 mm to 15 cm and length from 15 to 30 cm.
