Phosphating is the process of converting a steel surface to iron phosphate. This is mostly used as a pretreatment method in conjunction with another method of corrosion protection. A layer of phosphate coating typically includes iron, zinc or manganese crystals. Phosphating is also known as phophatizing and phosphate conversion coating.

A typical process of manufacture consists of three stages: grinding a mixture of limestone and clay or shale to make a fine "rawmix" (see Rawmill);; heating the rawmix to sintering temperature (up to 1450 °C) in a cement kiln;; grinding the resulting clinker to make cement (see Cement mill).; In the second stage, the rawmix is fed into the kiln and gradually heated by contact with the hot ...
• Precast concrete panels have a distinct advantage over other materials such as brick, concrete masonry, cast-in-place concrete and EIFS. • Because precast panels are manufactured well in advance of installation, they are ready for transportation to the job site at a moment's notice. Ease of Installation
Fiberglass rebar is a reinforcing material intended to be used in concrete to replace traditional steel type reinforcement. Made from Fiberglass rovings to give the material it's strength, and a vinyl ester resin to ensure its long life, Fiberglass rebar has been used for over 20 years with excellent results.

The basic design for lightweight concrete is covered in Eurocode 2 Part 1-1, with section 11 having particular rules required for lightweight aggregate concretes. Concrete is considered to be lightweight is the density is not more than 2200kg/m 3 (the density of normal weight concrete is assumed to be between 2300kg/m 3 and 2400kg/m 3 ) and a ...
What is Lightweight Concrete Types Uses and Advantages,Lightweight concrete mixture is made with a lightweight coarse aggregate and sometimes a portion or entire fine aggregates may be lightweight instead of normal aggregates Structural lightweight concrete has an inplace density unit weight on the order of 90 to 115 lb ft³ 1440 to 1840 kgm³
Feb 24, 2020· In a concrete mixer, add the determined amount of water and then the concrete mix. You can also mix this in a wheelbarrow with a shovel. Use as little water as possible. Water makes the concrete more maneuverable but it also weakens the constitution of the final product. A drier mix makes the concrete more crack resistant. Turn on the machine.
