· Crushed stone is mainly used in commercial or residential projects, or for road construction in the development of roads and highways. Sizes of Crushed Stone in Construction: 1 ½" – This size of crushed stone is mostly used for roads in construction. It''s also used in residential settings as patio, driveway, slab, and walkway material.
This inorganic bulk material that looks like a small crushed stone is widely used in many spheres of human activity. Different types of crushed stone, depending on its physical and technical characteristics, are used in the overhaul and restoration construction of buildings, roads, railway tracks, the production of concrete goods, landscape planning.
Some of the most common crushed stone sizes include: >1/4" – At less than a quarter of an inch in size, this type of crushed stone (usually stone grits or stone dust) can be used for traction, for filling in void spaces between other aggregate materials, or even for use as a binding agent.
In Civil Engineering and Construction Industry, crushed stones are known as aggregates and are the basic materials in modern construction work. The current methods for crushing stones to produce aggregates are characterized by the use of large, expensive and centralised crushing plants, which are beyond the reach of small scale entrepreneurs.

· It is porous and spongy in its structure. It is soft and workable hence quarrying of laterite is easy. It has low crushing strength which is about 1.8 to 3.0 MPa. When it is decomposed it turns into moorum which is widely used for road construction. Uses Laterite is
· Characteristics of Good Building Stones. Every building stone which is used for construction, cannot satisfy all the ideal requirements. For example, when the stone satisfies the requirement of strength and durability, it may not do the same with other necessities such as ease of dressing. Hence it is the job of the site engineer to look into ...
The Effect of Aggregate Properties on Concrete Concrete is a mixture of cementious material, aggregate, and water. Aggregate is commonly considered inert filler, which accounts for 60 to 80 percent of the volume and 70 to 85 percent of the weight of concrete.
· 3. INTRODUCTION • Rock is a solid cumulative of minerals located in the earth''s lithosphere.They have been used by mankind through history as a basic construction material. • There are huge variation within each type of rocks,depending on their engineering properties rocks have been used in various construction works.
· Aggregates Definition - Aggregate is a type of material used in construction, including sand, gravel, crushed stones etc. 19. Requirements of Good Aggregates • It should be chemically inactive • It should be sufficiently strong • It should be hard enough • It should be durable • It should have rough surface • It should be of proper shape • It should have limited pores
