Cement is basically manufactured by mixture of shell, limestone, calcium, marl or chalk, slate, silica sand, shale, clay, iron ore and blast furnace slag. Substance that look like rock will be formed after being heated at a reasonably high temperature, of course, normally it will be presented into fine powder which also known as cement. Concrete is another paste form of substance resulted from mixture of hardening materials such as rock, sand with water. Cement supplier Malaysia will normally conduct lab test in order to ensure the industry standard can be fulfilled at all time since structural concrete is so important to a building, elements that must have strict compliance to specification for safety purpose regardless of assets or human.
Cement supplier in Malaysia usually apply dry method to manufacture the Ordinary Portland Cement (OPC), the basic raw material will be quarried, such as clay, limestone and rock. Rock shall be crushed to not more than 6 inches and subsequently reduce to less than 3inches. Other ingredients will be combined with the crushed rock including fly ash, iron ore, cement kiln and many other materials. One of the reason why cement supplier Malaysia will put in cement kiln because it can heat up the ingredients to around 1,500 celcius in the large cylindrical steel rotary kiln that made up of custom made firebrick. The kiln has a height of maybe more than a 40-storey building, mounted with some kind of degree inclining to a horizontal one.
Concrete supplier Malaysia has a common batching plant setup where the lower end has a consistent roaring flame blast powered by certain fuel types such as oil, coal or gas burning within a precision in controlling, while higher end has to be fed with slurry and ground raw material. The marble-sized grey ball that comes out from kiln is known as clinker, clinker is those remaining element that could not shaped into gas form while material forwards through kiln. After that, the discharged clinker from kiln’s lower end will be taken down to temperature that is manageable through cooling systems, while cooler’s heating air returns back to the kiln in order to achieve fuel saving and efficiency in burning.
Subsequently, gypsum and limestone will be mixed and grinded with the clinker, typically 150 billion grains contents will be found in 1 pound of fine cement. After the final process done, cement will then be transportable to ready-mix concrete companies or other kind of clients in construction industry. Despite the popularity of dry process, but wet process is also common to be applied by concrete supplier in Malaysia for some countries. Dry and wet processes are about the same apart from raw materials will be water-grounded even before feeding into the kiln.
Cement is kind of binder for substance to set, adhere and harden other materials and it is uncommon to be applied alone, usually to bind those aggregate such as gravel and sand together. Fine aggregate cement mixture can be utilized for mortar while gravel and sand aggregates can be used for concrete. Cement that being applied in construction usually are calcium silicate or lime based that is inorganic, hydraulic and non-hydraulic characters, it depends on the cement capability to complete setting in water presence. Concrete supplier Malaysia normally can supply both at an affordable price, depends mainly on the requirement.
Although more common to have hydraulic cement (Portland cement) in the market, but non-hydraulic cement has their market too, it will not set in underwater or wet condition yet it set as it dries and react with CO2 in the air, chemical resistances after being set. Hydraulic cement become adhesive after being set as a result of chemical reaction, integrating water and those dry elements. Concrete supplier in Malaysia claims that this type of cement is safe to use as it has high durability in water, chemical resistant due to the low solubility of water of these mineral hydration. Consequently, it allows the hardened component able to prevent attack from chemical, at the same time tolerate wet condition setting or even under the water.
Ready-Mix Concrete (Premix Concrete)
There are many premix concrete batch plant in Malaysia, they are basically delivered in two ways, either in dry ready mix form and concrete mixing on site or sending the plastic concrete form to the site by in-transit mixer or barrel truck. The ready-mix concrete supplier in Malaysia works in different way, batch plant enables different kind of concrete mixture to be produced based on client requirement, and it is basically a combination of sand, water, cement and rock together by adjusting their weight ratio. Premix concrete is very popular because it helps to save time and cost, in term of the effort and time spent on the site mixing.
Since premix concrete supplier in Malaysia does have a standard quality compliance to be met, the level of consistency provides high safety value to the construction site. Generally speaking, it will last about 20 years more than road that made up of asphalt at the condition of high traffic.
According to cement supplier in Malaysia, premix concrete has more acceptance level because contractor has high confidence level compared to mixing works to be done on site. Ever since 60years ago where most countries have stability (no war, for example), the number of batching plants in the global countries is growing tremendously; when economy grows, population grows due to the demand of building and therefore, concrete demand from construction grows.
Concrete supplier in Malaysia normally is having relatively full schedule in production and delivery where contractors must place order advanced in order to avoid any unnecessary disappointment due to the concrete supply delay. Concrete is a key to foundation, structure and infrastructure, it must be planned well so that the project can be completed on time (time is cost for construction project). Cement supplier Malaysia is required to work closely with their client, either in term of premix, ordinary cement or aggregates such as rock, sand, gravel and other elements.
