on-site concrete aggravating. Bags of cement‚ sand‚ aggregate and possibly other additives must be delivered to the construction area. A supply of clean water is also necessary‚ along with a rented concrete mixing hopper. Even after all the dusty and heavy ingredients have been loaded into the hopper‚ there may occur the problem of erroneous water-cement ratio. One common solution to this messy and time-consuming problem is “READYMIX CONCRETE”. 1.1 Readymix Concrete Ready-mix concrete (RMC) is

About Cement:Cement was invented in 1824 by Joaeph Aspdin‚ an English Mason. He named the product as Portland cement as its color resembled to the rock found in Portland‚ a place in England. Concrete is the second most used commodity in the world after water. During 2000-2001‚ it is estimated nearly 1 ton of concrete is used by each person on earth. The production of cement is presently estimated at 2000 Million Tons. The strength of cement when it was invented was about 10 MPa which has Continuously

considered to contribute to structural strength (see Table 3.17 for minimum thickness): 1) as a series of concrete ribs cast in-situ between blocks which remain part of the completed structure; the tops of the ribs are connected by a topping of concrete of the same strength as that used in the ribs; 2) as a series of concrete ribs with topping cast on forms which may be removed after the concrete has set; 3) with a continuous top and bottom face but containing voids of rectangular‚ oval or other shape

FOUNDATION is the lowest supporting layer of a structure. * Purpose: Transfer the building load to the soil. * The size of the foundation is determined by the weight of the building and the load bearing capabilities of the soil. * When the load bearing capabilities of the soil is low‚ a footing is usually used. Types of Foundation 1. Shallows Foundations * Shallow foundations are those founded near to the finished ground surface; generally where the founding depth (Df) is less than
