英国人发明了它，法国人改良了它，中国人最需要它，水泥的发明历史，你了解吗？
历史上最早出现的类似于“水泥”的建筑胶凝材料，是距今5,000年的美索不达米亚人发明的，其主要成分是石灰、沙子和砾石，美索不达米亚也就是人类文明的起源地。
之后、古埃及人、古希腊人、古罗马人都通过就地取材对建筑胶凝材料进行了改进。古罗马人甚至用“石灰-火山灰-砂子”做的“罗马砂浆”，修建了大量的大理石建筑，其中最有名的就是罗马万神殿和卡拉卡拉大浴场。
1756年英国土木工程之父史密顿在修建灯塔过程中用黏土、石灰石制成水硬性石灰，能耐海水的冲刷。
1796年英国人派克发明了十几分钟就干的水泥，命名“罗马水泥”。
1822年，英国人福斯特发明了“英国水泥”。
1824年，英国政府发布了第一个“波特兰水泥”专利，当代建筑“粮食”由此诞生。

According to the forecast of the meteorological and hydrological department, the natural inflow of Xijiang and Beijiang rivers in the Pearl River Basin this winter and next spring is 10 to 30% less than that in normal years. Xijiang River is the core route for the export of gravel, cement, machine-made sand, stone powder and other materials from Guangxi to Guangdong. Taking the core Changzhou Lock on the Xijiang River as an example, in 2023, there were 61889 ships passing through the lock, and the cargo volume passing through the lock was 6800 tons 14203, with a year-on-year increase of 2.05% and 13.71% respectively. The main types of cargo were gravel, cement and stone powder, accounting for 40%, 15% and 12% of the cargo volume passing through the lock.
