The Development of Concrete Technology in Malaysia.
When we talk about concrete,what was in our mind? The giants pillars of Penang Bridge or the not so good MRR2 highway that have multiple of fracture because of corruption? *nobody knows about that for sure. For your information,concrete is a composite construction material, composed of cement (commonly Portland cement) and other cementitious materials such as fly ash and slag cement, aggregate (generally a coarse aggregate made of gravel or crushed rocks such as limestone, or granite, plus a fine aggregate such as sand), water and chemical admixtures. The word concrete comes from the Latin word "concretus" if I not mistaken. The meaning for the word is compact or condensed.
In Malaysia,concrete technologist done a lot of research to faces all the challenges that is possible to occurs and durable with the weather in Malaysia. For what I know,the mixure of water,cement,sand and aggregate must appropriate to ensure the sustainability and sustainable of the concrete itself. When the mixture,are lack of the ingredients,the concrete will lose it nature thus fracture may occur. In Malaysia,they have find a way in making the ordinary concrete smart and dynamic the BASF way. With this,the concrete will be more stable and pumpable to accelerate the pace of construction,high flowability for complex concrete structures and elements,higher durability specifications to extend the service life of the structure and wide adaptabilityof raw materials reduce pressure on the quality control of concrete production. In 10th Malaysia Plan,5percent of the new road are in concrete because it last longer than asphalt and bitumen.
Works Minister Datuk Shaziman Abu Mansor said the concrete roads would replace asphalt or bituminous roads which cost more as they depended on current oil prices.“Concrete surface have better content component value and cheaper to maintain. From the safety aspect, concrete roads are much brighter and safer in low-lit areas,” he told reporters after opening the Public Works Department (PWD) Senior officers’ Meeting here Monday.
He said that the PWD had proposed to the National Action Council on the need to allow companies awarded tenders for major projects to resubmit proposals on innovative method of construction without affecting the functions of buildings.
“This will benefit the government as well as the contractors. At the moment there are many new construction technologies at our disposal. We cannot be too rigid in building construction as it does not give leeway to contractors to be innovative and creative and provide feedbacks to the government,” he said.Shaziman said the feedbacks could help reduce the cost of building materials, machines, systems and services without affecting the specifications, construction period and the original function of the concrete roads projects. On staff relocation, he said the PWD should relocate staff whether they were architects, engineers or quantity surveyors based on their technical expertise and educational background. Shaziman said he proposed that senior officers to be appointed as enforcement superintendents of high-profile projects under the 10MP.“We have capable concrete roads experts. Ironically when they get promoted, they do managerial works but under the 10MP they will be entrusted with high-profile projects. When Malaysia government save more,the excessive of money maybe goes to the society but who knows?
*nukilan aku untuk disubmit tak lama dulu.hahaha
