| 摘要 |
The invention relates to a material that can accumulate heat energy at high temperatures without losing its structural capacities. The material is fundamentally concrete formed by a mixture of cement, aggregates and water by means of high-frequency vibration, and comprises a proportion of aggregates which corresponds to between 70% and 85% of the total volume of the dry mixture, where the aggregates are classed as fine aggregates having a diameter of less than 8mm and coarse aggregates having a diameter of between 8mm and 25mm, the granulometry of the dry mixture presenting deviations from the Bolomey curve of less than 5% in the end thirds of the granulometry and less than 10% in the middle third of the granulometry. |
