Selection of Stones for Building Construction
Once a stone has been selected on aesthetic basis, it is important than to ensure whether it exhibits the necessary physical properties and durability to remain in working condition for a long time. Confirm the traditional name of the stone and test it in the field for properties like streak, color, hardness etc. It is better to confirm whether the amount and quality of stone
How to Build a Stone Wall?
To assist in your stacking, sort the stone by size; setting aside the smallest pieces to use as shims (these will help level unsteady larger stones). Prepare for this activity by stretching well and always lift using your arms and legs, not your back Shims (shown far right), or smaller stones, help level unsteady larger pieces. Map out the design by digging a trench about 6" deep and as wide as
Applications & Uses of Building Stones in Civil Engineering
Stone being so important in the light of the above uses still is not widely used in construction. The reasons are: Stones are replaced by the increased use of RCC. Dressing of stones is time consuming Stones are not cheaply and conveniently available in plain areas. Marble is widely used in construction industry, for aesthetic purposes, beautification and strength. Nite, and
Properties of Stones and Tests Applied on Stones
The more compact grained and heavier a stone the harder it is. Due to alternate wetting and drying the resulting crushing strength can be reduced even up to 30-40%. Being dry stones allow more crushing strength than when wet. It is the ability of a stone to endure and maintain its essential and distinctive characteristics i.e. resistance to decay, strength and
Geological Classification and Characteristics of Stones
Sandstone, limestone, dolomite originally formed mainly in sea water, or lakes, from the remains of animals and plants, also from transportation and deposition of rock products. Geologically the stones can be classified as follows:.... A. Detrital is made from disintegrated pre-existing rock. B. Biogenetic is made from shells and other fossilized fragments. C. Chemical is made
Differences between stone and brick masonry
First of all, in brick masonry, brick is the smallest structural unit and in stone construction stone is the smallest structural unit. Stone masonry is usually used in rural areas and its best kind, which is very costly can be used for very strong construction. In brick masonry the size and shape of the brick matters a lot but not in stone masonry. The discontinuity of joints is important in both
Factors Affecting Strength, Hardness and Toughness of Stones
The composition of the compounds determines its hardness or softness. Stones containing Si, Na, K are poor while that containing Mg, Ca, and Fe are good, as they are harder. If the stone is composed of soft and unhardened materials it will result in a soft materials and vice versa. The amount of soft and hard material in a specific sample of stone also matters.
Selection of Stones for Building Construction
Being cheap, hard, durable and naturally good looking, stones are often used in construction but keeping in view the variable properties of stones of different types, there must be some criteria for the selection of stones for construction. The criteria is based upon the following parameters: Chemical composition of stone: Strength and hardness, Durability, Resistance
Types of Stone Masonry - Rubble Masonry and Ashlar Masonry
The art of building a structure in stone with any suitable masonry is called stone masonry. Stone masonry may be broadly classified into the following two types: 1. Rubble Masonry 2. Ashlar Masonry. The stone masonry in which either undressed or roughly dressed stone are laid in a suitable mortar is called rubble masonry. In this masonry the joints are not of uniform
Minerals, Rocks and Stones used in Construction
Rocks normally consist of several minerals, some essential, some accessory. A rock may be thought of as a "mineral environment." Each rock type was formed under certain specific conditions, resulting in the formation of a fairly predictable group of minerals. Rocks fall into three classes according to their origin: Igneous, Sedimentary, Metamorphic. Following are some rocks
