What Is The Difference Between Nominal Mix And Design Mix?

-
Image
Nominal Mix  1- When the concrete is produced by taking standard arbitrary proportions of concrete ingredients, it is known as nominal mix concrete.  2- The nominal mix is a mix considering all ratio in the volume where Strength and cost of concrete and strength of concrete varies. 3- It is Prescriptive type concrete.  4- It is used in ordinary concrete involving concrete grade not higher than M20.  5- There is no quality control. 6- Water cement ratio is based on durability criteria, experience and practical trials.  7- Water content can be modified by slump value (field-based test)  8- No entrapped air content is considered.  9. Trial mixes concept is mentioned. Design Mix  1-lt can be defined as the process of selecting suitable ingredients of concrete and determining their relative proportions with the object of producing concrete of certain minimum strength and durability as economically as possible. 2- Design mix is a mix considering all ratio

Types Of Pipes Used In Water Supply System/Plumbing

  Types Of Pipes:  The types of pipes commonly used in water distribution or plumbing system are described below. 1. Cast Iron Pipes:  Cast iron pipes or CI pipes are broadly utilized for distribution of water because they are less expensive, corrosion resistant, and long lasting. Cl pipes are mainly produced by following four techniques.  1. Horizontally cast (MC ware pipes)  2. Vertically cast (Pit cast in sand molds) 3. Centrifugally cast in sand lines molds spun type.  4. Centrifugally cast in water- cooled molds.  Uses of horizontally cast CI pipes are presently pretty much outdated, that's why they are infrequently produced these days. Centrifugally cast pipes are most widely used because they have more grained dense structure and uniform thickness. Generally, CI pipes are 3-6 m long, so much heavy, and require extra care to avoid from damaging while transporting and creating connections. 2. Steel Pipes:   Steel pipes are utilized in water mains circumstances where the pipes

Types Of Sand Used In Construction Works

  What Is Sand? Sand is a material obtained naturally from the locations like rivers, seas, beaches, and desserts. Sand is a granular material which consists of particles of finely divided rock. The major and the most common component of sand is silica (Si02 or Silicon dioxide), found usually in the form of quartz. Sand, consisting of tiny particles, is formed by the weathering of rocks. In this article, we will briefly discuss different types of sand used in construction.  Usually, the major source of sand is river, sea, etc. from where the sand can be obtained naturally. Other than such natural sources of sand, it can also be manufactured artificially, about which we will further learn in detail. Particles of sand are coarser than silt and finer than gravels. So, according to the Bureau of Indian Standards (BIS), earlier known as the Indian Standard Institution (ISI), the size of sand particles ranges from 0.075 mm to 4.75 mm. Based on the size of sand particles, it is further subdiv
