What are the properties of good building stones?
nikeetasharma
Properties of good building stone ; Texture :Â A good building stones must compose fine crystalline structure which should be free from cavities, cracks or patches of soft or loose material. Stones with such texture are so strong and durable. Toughness Index :Â If the value of toughness index comes beRead more

What are the purpose and usage of Plasticizers?Â
nikeetasharma
Plasticizers are generally colorless liquids which are relatively nonvolatile. In other words, plasticizer is a substance that is added to the material to make it softer and more flexible. Plasticizers are commonly added to polymers such as plastics and rubbers, to facilitate the handling of the rawRead more

The purpose and usage of plasticizer are as follows ;
Which cement is best for concrete slab construction? OPC or PPC?
nikeetasharma
For the construction of concrete slab both the OPC & PPC cement can be used. OPC is the basic form of cement with 95% cement clinkers and 5% gypsum and commonly used in industrial and large construction. OPC cement gives high compressive strength at early stages and at 28 days. OPC cement also hRead more
For the construction of concrete slab both the OPC & PPC cement can be used. OPC is the basic form of cement with 95% cement clinkers and 5% gypsum and commonly used in industrial and large construction. OPC cement gives high compressive strength at early stages and at 28 days. OPC cement also has increased workability and higher strength at later stages. Hence, it has early strength and also has cost saving advantages can generally used for the construction of concrete slab. OPC cement can also be recommended for the construction of columns, beams, etc.
On the other hand, PPC cement is made up of 75-77% cement clinker, 20% flyash and 3-5% gypsum. They are commonly used for small residential construction. PPC is recommended for brick masonry, plastering, tiling and waterproofing works. It has slower rate of heat of hydration. PPC is prone to less cracks and reduced shrinkage and also gives better workability and finishing. Thus, PPC is only used where the possibilities of sulphate attack is higher as it is said to be the good sulphate resistor.
Hence, both OPC & PPC can be a substitute to each other but only with a better quality control & by adopting best construction practices. So, for the construction of concrete slab both the OPC & PPC cement can be used.

nikeetasharma
The test of reinforcement bar at site are as follows; The dia of reinforced bar should not vary. Bars should not be brittle in nature.It should no break in pieces during bending. The pitch length between the twist should be 8 - 12 times that of the nominal dia of bar. The length of the bar should beRead more

What is murrum soil?
nikeetasharma
Murrum soil is the soil of humid tropical or equatorial zones. It is characterised by the deep weathered layer fom which silica has been leached. Thus, there is no humus, but an accumulation of aluminium and iron oxides and hydroxides. These soils are reddish in color & is imparted by the iron cRead more
Murrum soil is the soil of humid tropical or equatorial zones. It is characterised by the deep weathered layer fom which silica has been leached. Thus, there is no humus, but an accumulation of aluminium and iron oxides and hydroxides. These soils are reddish in color & is imparted by the iron compounds. For building huts and paths, they are good materials, as it can be compacted easily to form hard surfaces.
Murrum soil comes under laterite soil. Laterite is a soil and a rock type rich in iron and aluminium. Murrum soil is also referred as being a rock type but it is not a rock.
The approximate density of murrum soil is 1.8 gm/cc.
Explain Arch Dam and Buttress Dam?
nikeetasharma
Arch Dam ; Arch dam can be defined as a solid wall, curved in plan, standing across the entire width of the river valley in a single span. The body of arch dam is generally made of cement concrete. Thus, arch dam is just a curved beam, the ends of which are restrained and the way in which the loadsRead more

Arch dam can be defined as a solid wall, curved in plan, standing across the entire width of the river valley in a single span. The body of arch dam is generally made of cement concrete. Thus, arch dam is just a curved beam, the ends of which are restrained and the way in which the loads are resisted is termed a arch action.
Buttress Dam ;
A buttress dam or hollow dam with a solid, water-tight upstream side that is supported at intervals on the downstream side by a series of buttresses or supports. A buttress dam envisages to reduce the total volume of concrete by constricting the material where the stresses are higher and other undesirable features of gravity dam but has higher cement content per cubic metre of concrete than a gravity dam.

What is the important of Proctor Compaction Test?
nikeetasharma
Compaction test of soil is carried out using Proctor's test for understanding the compaction characteristics of different soils with change in moisture content. The ability for compacting a soil depends on the water content of the soil. Thus, water acts as a lubricant between the soil grains howeverRead more
Compaction test of soil is carried out using Proctor’s test for understanding the compaction characteristics of different soils with change in moisture content. The ability for compacting a soil depends on the water content of the soil. Thus, water acts as a lubricant between the soil grains however as its content increases the water may occupy the entire pores. Since it is relatively incompressible in comparison to the air it may restrict compaction. Proctor compaction test is used to determine the optimum moisture content during compaction which gives the greatest soil density.
