Or perhaps, why add sugar to concrete? In today's video, we will explore this intriguing and controversial technique used in construction. Let's discover the myths, truths and real effects of using sugar in concrete. Get ready for a fascinating journey into the world of materials engineering and chemistry! 🔍 What will you learn in this video?: We recently made a video about the use of detergent on concrete and mortar, which generated a lot of controversial comments. Now, we decided to tackle another peculiar technique: adding sugar to concrete. Is this a good idea? First, let's understand the reason for putting sugar in cement. Adding sugar to concrete may seem strange, but it is a practice used in certain specific situations in construction. We will explain how sugar acts as a water-reducing agent, helping to control the amount of water used in the mix and reducing the porosity of the concrete. 🌡️ Applications in different climates: Cold Climates: In cold regions, concrete can suffer damage due to freezing and thawing. Sugar helps make concrete more resistant to these cycles. Hot Climates: In hot climates, sugar is used to delay the setting time of concrete, controlling the temperature during the hardening process and preventing overheating and cracking. 📊 Case study: We referenced the Science Direct study, “Effect of sugar dosage on setting time, microstructure and strength of Type I and Type V Portland cements”, to analyze the effects of sugar on the setting time and strength of concrete. We will show graphs that illustrate how different percentages of sugar affect concrete. ⚠️ Care and Recommendations: It is crucial not to exceed the amount of 0.05% sugar in the cement, as larger amounts can reduce the strength of the concrete. We also discuss adverse effects, such as reduced initial strength and increased porosity. 🔧 Alternatives to using sugar: If you are considering using sugar to delay setting time, know that there are tried and approved delaying additives for this purpose. Furthermore, for constructions such as barbecues and ovens, the use of refractory concrete is recommended. 📢 Participate!: Have you ever seen someone adding sugar to concrete?
