Binding agents, often known as a binder, happens to be a compound that is used to bind materials together to provide structural constancy. Binding agents bind filler powder, fibres, and other material together by hardening chemically or physically.
Binding agents have long been employed in building; for example, straw and natural fibres have been utilised to stiffen clay in wattle-and-daub construction. Cement, which is used to build concrete, is a highly frequent binding agent utilised in modern construction. Bitumen binder, which is used in asphalt pavements, and clay, which is used to bind bricks, are two more common examples.
In underground and underwater engineering projects, hydraulic binding agents are frequently used. They continue to retain and boost their strength when mixed with water. Portland cement, blast-furnace cement, pozzolanic cement, hydraulic lime, alumina and expanding cement, and other materials are examples.
After combining in air rather than water, air-entrained binding agents use to harden and keep their strength. Gypsum cement, air-hardening lime, magnesium cement, and other materials are examples.
Acid-resistant binding agents can maintain their strength in the presence of acids after mixing in air, resulting in a variety of acid-resistant cements such as silicon fluoride cement, quartz cement, and so on.
Binding agents can also be ‘organic,’ meaning they are made of organic materials like asphalt, bitumen, pitch, polyvinylacetate, and resins. They change from a pliable to a rigid state under the influence of physical or chemical processes.
The success of Portland cement concrete, as well as its widespread acceptance and use, is largely due to developments in cement science, which played a key part in its invention and in resolving many of the issues that have emerged during its use. The variety of Portland cement binders will continue to grow as the globe draws closer to building more sustainable methods for the manufacturing, application, and use of Portland cement concrete. That is, cement compositions will become more customised to specific purposes as well as a more sustainable use of existing materials, including the utilisation of waste materials and industrial byproducts as cement substitutes. The growing diversity of cement types, as well as the challenges that will inevitably occur as a result of their use, will increase the demand for cement science to give answers and solutions. This study examines the accomplishments and shortcomings of cement binder Selangor, emphasising the importance of cement science in their development and in giving answers to present and potential future difficulties.

Hydraulic-setting binders, in combination with various fillers and fibres, should be used to make a variety of roofing materials, such as planks, boards, blocks, shingles, and so on. Hydraulic-setting binders must account for a significant amount of the composition due to the nature of the setting mechanisms, hydration and crystallisation. Furthermore, the composition’s density is usually high; otherwise, the composition’s strength will suffer.
Except in the densest uses or when slopes are such that drainage is rapid, hydraulic-setting binders are not waterproof, and some may deteriorate, usually by losing strength, when wet. As a result, this type of binder must be used in conjunction with additional waterproofing, be exceedingly dense, or be laid on steep enough slopes to allow for quick drainage.
Slurried hydraulic-setting binders are combined with fibre, filler, and other materials before being formed in a mould or press. Excess water reduces the strength of the slurry and mix, therefore use only enough to slurry and mix. To get maximum strength, the produced roofing material must be cured for several days or weeks. To speed up the cure, either wet curing at room temperature or alternative elevated-temperature techniques can be used. The finished product is dried after it has been cured.
