Why do workers add sugar to cement? Does this do anything? Because cement will harden quickly in hot weather, in order to slow down the hardening speed of cement, workers usually use cost-effective white sugar as a buffer. When I was building a house in my hometown, I wonder if my friends have noticed such a strange phenomenon, that is, many workers will add sugar to the cement. Why do the workers add sugar to the cement? The main components of cement are limestone, clay, gypsum and sand, which react chemically with river water. Cement powder eventually generates hydrated calcium silicate. If sugar is added to it, tricalcium silicate particles, the main component of cement, will be adsorbed. The calcium silicate hydrate on the surface of the particles will also be eliminated, and the cement will no longer become cement. So white sugar has become a magical material, used to control the setting time of cement, but not all sugar can slow down the setting time of cement. Some sugars can be used as thickeners, such as methyl glucose, which is often used as a tool and dendritic mediator in the synthesis of polyester polyols. There are many commercial retarders on the market now, but most of them are expensive. Or is the price of white sugar more clear? In hot weather with higher temperatures. Cement will harden quickly. In order to slow down the hardening speed of cement, workers usually use more affordable white sugar as a buffer. Make sure that under normal construction conditions, the cement will not harden quickly. Sometimes you will see workers spraying liquid on the surface of the cement. Yes, what is sprayed is sugar water. This is to create a matte effect of rough variations, and at the same time, you will also see white sugar in the cement mixer car. This is because accidents such as traffic jams often occur, and sugar is used to prevent cement from solidifying. So what else is there to do with sugar and cement? The first sugar can enhance the impermeability and fluidity of concrete, because the concrete is too sticky and sticks together, making it difficult to absorb when pouring the mold. Secondly, the density of concrete is relatively high and the fluidity is relatively poor. It is difficult to press the angle during construction, so the construction quality of concrete will be greatly affected. It has a great impact on some construction operations with higher requirements, such as water tanks with earthquake resistance requirements, granaries and cement warehouses with air tightness requirements. Although it can be solved by increasing the amount of water and increasing the spreading degree of the concrete plate, it will be inevitable. It has a great adverse effect on the strength and permeability of concrete. At this time, sugar plays an extremely important role. Sugar can solve this problem. When using this method, we must control the amount of sugar, not too much or too little. If there is too much, the concrete will lose its compressive resistance, so there is a saying that sugar is also the nemesis of cement. Let me give you another example. During World War II, everyone should know that French soldiers used sugar to add to cement. I would also like to remind all construction site team members to be careful when drinking milk tea or sugar water on the construction site. Be sure not to let cement taste this delicacy, as it will cause certain losses if you are not careful.
