Today, the construction industry is focusing on the use of sustainable materials due to their environmental impact. because of their environmental impact. Concrete is widely used in construction due to its diverse properties, but one of its components, cement, composed mainly of clinker, causes significant CO2 pollution. clinker causes significant CO2 pollution. Therefore, the possibility of partially substituting this the possibility of partially substituting this material is being investigated. One example is calcined diatomaceous calcined diatoms, which are mainly composed of diatomite layers. The objective of this The objective of this study is to evaluate the properties of conventional concrete with the incorporation of calcined diatoms in proportions of 5%. calcined diatoms in proportions of 5%, 10% and 15%. For this purpose, tests were carried out in the fresh and hardened state. and hardened state. In general, the properties improve with respect to the standard mix for a 5% by weight substitution of cement with diatomaceous earth. 5% by weight replacement of cement by calcined diatomite. Calcined diatoms can be used in the production of lightweight concrete, since they reduce its density by 17 kg/m3. In terms of compressive strength, a 9% increase was observed with the addition of 5% calcined diatoms. of calcined diatomaceous earth compared to conventional concrete, thanks to its high pozzolanic activity. pozzolanic activity. In terms of durability, improvements were found when using 5% calcined diatomaceous earth as compared to conventional concrete, due to its high pozzolanic activity. calcined diatomaceous earth. The diatomite, despite increasing the production cost by 3% per cubic meter, improves the properties of the concrete. cubic meter, improves the properties of the concrete due to its low density, high pozzolanic and microscopic activity. pozzolanic activity and microscopic size.
