Recent advances in the technology of civil engineering materials have resulted in the development of better quality, more economical, and safer materials. These materials are commonly referred to as highperformance materials. Because more is known about the molecular structure of materials and because of the continuous research efforts by scientists .
· Marginal materials are these materials that because of either their poor compaction, consolidation, or swelling characteristics would not normally be used as backfill if sources of suitable material were available. Material considered to be marginal include finegrained soils of high plasticity and expansive clays. The decision to use marginal materials .
Based on the grain size of the particle, sand is classified as Fine Sand ( to ), Medium Sand ( to 2mm), and Coarse Sand ( mm to ) Based on origin, sand is classified as Pit sand, River sand, Sea sand, and manufactured sand. Fig. Grain size distribution of sand used in building construction.
Filler materials are gaining widespread popularity and becoming very important because they help in increasing some of the mix properties and also lower the usage of binder which is usually more expensive Here is the table showing some common filler materials along with binders. Material: Binder: Filler: Importance of filler: Concrete: cement: gravel, stone, sand: cheaper: Drywall: gypsum ...

Proper calculation and relative proportioning of materials are important to produce a good quality concrete. Let's see some simple techniques used by engineers to calculate cement, sand, coarse aggregate (gravel or Jalli) and water needed to produce different grades of concrete, like M5,, M10, M15 and M20.
The appliions of stones have greatly influenced the works of Civil Engineering. Stones have been of very great importance as a building material since the prehistoric age. For the structural purpose, granite, gneiss, trap, sandstone, limestone, marble, quartzite and slate are most useful. For manufacture purpose, items and materials from natural stones are classified as .
These stones are derived from sedimentary rocks. These stones are found in layers one above another Limestone and sandstones are the stratified stone. Unstratified Stones. These stones do not show any types of layers. Granite, marble, trap, etc. are the unstratified stones. What are the Different types of rocks? Geological classifiion of stone
· The occurrence and distribution of soils in nature varies from loion to loion. The type of soil depends on the rock type, its mineral constituents and the climatic regime of the area.
