[编译]水泥价格飙升，丹格特水泥综合收益总额增长400%以上
2023年一季度，尼日利亚水泥价格大幅攀升至10000-15000奈拉/袋（相当于1000-1500元/吨），同比近乎翻番。当地最大的水泥生产商丹格特水泥的销售收入创造历史新高……

在Holcim孟加拉国公司组织的研讨会上，有关研究人员说，筑路时，用水泥代替沥青可使成本减少50％。他说，用水泥筑的路不象用沥青筑的一样需要经常维护，这能减少成本。这项技术通常在发达国家使用。
孟加拉国交通部长Nazmul Huda，Holcim孟加拉国公司经理在该研讨会上发了言。交通部长说，政府有可能在今后的公路建设中采用该技术。具有30年水泥筑路经验的埃德温·皮特里先生作了有关公路稳定性的报告。
据皮特里所说，这项技术可以减少公路倾斜，避免湿气的进入，改善公路的切变强度。Holcim公司人员说，他们公司的水泥已经应用于一些桥梁建设中。

Use of cement in road construction instead of bitumen can reduce costs by 50 percent, a Roads and Highways Department (R&HD) engineer who is conducting a research on the technology, told a seminar yesterday.
He said roads made by cement do not require maintenance frequently as needed by those constructed by bitumen and thus use of cement can reduce cost. The technology is widely used in many developed countries, he informed the seminar organised by Holcim (Bangladesh) Ltd, a leading cement manufacturer, in Dhaka.
Communications Minister Nazmul Huda, R&HD Chief Engineer SK Rabiul Islam and Holcim (Bangladesh) Managing Director Ramit Budhraja also spoke at the function.
The minister said the government will use the technology in its future road construction projects if it is found beneficial.
Edwin Petrie, a London-based expert who has 30-year experience in cement-based technology, made a presentation on 'Use of Cement in Road Stabilisation.'
According to Petrie, the technology reduces deflection of roads, prevents ingress of moisture and improves shear strength of the road.
Sharing his experience of building cement-stabilised roads in Australia, he said Bangladesh could be benefited through applying the new concept. "But before that a lot of research should be conducted," he argued.
Holcim MD Ramit Budhraja said his company's cement has been used in constructing Jamuna, Bhairab and Paksey bridges. The proposed Rupsha Bridge will also be built by Holcim cement, he added.
