Types of Glass

Glass a complex form of of silicate can be classified according to its chemical composition into the following types:

1. soda-lime-Silica Glasses : This type of glass are used in the manufacturer of Glass containers produced by blowing, molding, and pressing and in special shapes such as electric bulb 💡

2. Silica Glass (Fused silica) : This belongs to one of the most important single oxide glasses suitable for use as lab ware.

3. Borosilicate Glasses : The presence of notice oxide,  which act as a flux as well as a glass former, gives Borosilicate glasses a low coefficient of thermal expansion and shock resistance. It's greatly used in laboratory and medical ware.

4. Lead Glasses: The presence of lead oxide (PbO) acts as a flux and a modifier,they have low melting and working point but with high refractive indices and densities...mostly use as optical components, for radiation shielding and as technical glasses.

5.  Alumino-silicate Glasses : The hardening effect if this type of glasses due to the presence Al2O3 which improve chemical durability and resistance to devitrification.  Example is E-glass used in glass fibers manufacture.

Construction Procedure of Surface Road Side Drainage-PART 1 (with picture)

Surface water ( i.e., rain water) that falls on the ground surface such as; open field, paved areas or road surface, roof tops etc are channeled to a main drain naturally or through a constructed channel which is referred to as drainage. Procedure for construction of a common drainage (trench) (1m x 1m U drainage) (reinforced). includes; I.       Marking Of Alignment: The surveyor marked out the alignment for the trench to be dug. II.       Digging/Excavation: The surveyor marked out the dept of the trench to be excavated with a mechanical excavating machine. For a 1m x 1m drainage, the mathematical process of obtaining the required dept is to sum together the dept of the required drain + base + blinding. For dept:  A drain of dept1000 mm, base of 150 mm and blinding of 50 mm. Hence 1000mm + 150mm + 50mm = 1200mm (1.2 m) So an excavation of 1200mm (1.2m) is required...

Construction Procedure of Surface Road Side Drainage-PART 2 (with picture)

  V.        Next step is laying of concrete base on the blinded surface and the positioned reinforcement. A concrete base of 150 mm is to be laid or cast on the blinded floor, concrete grade C20 of ratio 1:2:4 is allowed (See concrete grading and mix ratio). A guiding panel is placed into position to guild in the laying of the concrete base in order to achieve a uniformly alignment base edge, thickness and width, also to manage concrete material while pouring. The base is cast with the U shape reinforcement bottom in between the concrete base achieving concrete cover below and above.   VI.        After setting and drying of the concrete base, next is to position the side wall panel form work. The floor base is marked to give the required one meter (1000 mm) internal width where the panel will be positioned. The panel wall spacing is 100mm, and wall height of 1000mm (1 meter), the pan...

Setting out of a building

A building is set out in order to accurately define the outline and width of the excavation and to determine the center line of the proposed building walls, so that construction according to the building professionals drawing (the architectural plan) plan can be transfer into the ground, this building process is called setting out of building. The center line method of setting out is generally preferred and adopted Setting out can be a very complex engineering process but with need experience its quite easy. Experienced engineer and surveyors are those involved in setting out of structures, in large projects, services of land surveyors are required for more accurate transfer of levels and angles in setting out with the aid of a Theodolite to decided point around the building area But we are going to concern ourselves with the most common setting out method ·          Setting out using pegging ·      ...
