Method for predicting the compressive strength of concrete and mortar containing fly ash |
| abstract |
The present invention relates to concrete, mortar and other hardenable mixtures comprising cement and fly ash for use in construction. The invention also relates to hardenable mixtures comprising cement and fly ash which can achieve greater compressive strength than hardenable mixtures containing only concrete over the time period relevant for the construction. In specific embotiments, concrete and mortar containing about 15% to 25% fly ash as a replacement for cement, which are capable of meeting design specifications required for building and highway construction, are provided. Such materials can thus significantly reduce construction costs. |
