While on site, a site engineer must ensure that the brickwork is going on as per quality requirements. Some of the general requirements of quality of brickwork are mentioned below. Use this as a checklist while executing brickwork. The thickness of joint in brick masonry should not exceed 1 cm. The face joints should be raked to a depth of 15 mm by raking tool when the mortar is still green so as to provide proper key for plaster or pointing. Brickwork should be taken up in layers not exceeding one meter height at a time. Check that the brick work is in plumb. Check that the brick courses are in level. Check the quality of bricks with specific reference to Strength Efflorescence Dimensional accuracy Water absorption Check that no brick bats are used as queen closer. Check strength of mortar by scratching with sharp instrument like screw driver. Check quality of sand in mortar. (Test for fineness modulus and silt content). Check mixing of mortar whether do

Starbucks’ whiskey-flavored drink is now available in New York — but the only buzz you’ll get will be from the caffeine. It’s not exacly an Irish coffee, so don’t get too excited. There’s no booze in this java. Instead, the chain’s Whiskey Barrel-Aged Cold Brew is made by steeping green, unroasted Sulawesi coffee beans from Indonesia in empty oak barrels that once held aged whiskey, so the beans soak up the flavor.

Starbucks Reserve bars are high-end coffee bars and the Roastery is a large Starbucks loc

CAUSES OF DISINTEGRATION OF CONCRETE The primary reasons that cause disintegration of concrete member are desribed below. DISINTEGRATION OF CONCRETE 1.  SULPHATE ATTACK Soluble sulphates are present in Ground water Soil Clay bricks Soluble sulphates react with Tricalcium Aluminate of cement I n the presence of moisture and form products which occupy much bigger volume than that of original constituents and so expansive reaction results causing disintegration and weakening of concrete, masonry, plaster and formation of cracks. The reaction is very slow and cracks start coming to notice after 2 to 3 years. These reactions to take place, the presence of following three things are necessary Soluble Sulphate Tricalcium Aluminate Moisture As per this, the following components of building are more liable to be affected by sulphate attack. Concrete and masonry in foundation, especially where water table is quite high and concrete and masonry remain in contact with wat
