| Title of the article | On the possibility of the use of sludge produced from concrete waste recycling |
| Abstract. | To improve the quality of building materials various types of modifiers are used. Modern trend of modification of cement concrete is the use of nanoscale additives. There are different types and methods of obtaining the nano-additives, but they are quite expensive. To reduce the cost on receipt of such additives sludge of various industries can be used. In this work an attempt was made to obtain nanomodifiers from the sludge obtained after the recycling of the concrete mix. The main component of the sludge are prohydrated cement particles. Additional treatment of the sludge in laboratory installation of dispersing has reduced the size of the particles, but the particle diameter less than 100 nm in the end did not happen. The treated sludge can reduce the setting time of the cement paste, to increase the strength of concrete on the first day and subsequent stages of hardening. |
