Siam Research & Innovation Co. Ltd. has invested in an Atlas lab scale chemistry reactor from Syrris to investigate the kinetics of cement hydration and the interaction of admixtures.
Ms. Wanjana Wannaphahoun, a researcher at Siam Research & Innovation explained:
“We perform research and development for SCG, one of the largest cement manufacturers in Thailand. It is important that the end products are high quality and, to achieve this, we enhance the composition of the cementitious mixture – cement paste, mortar, and concrete – by adding extra materials to modify its performance. In 2010, we purchased an Atlas reactor which helps with this work and is used regularly for a wide variety of reactions. The Atlas system logs all set points and sensor data, allowing us to prepare materials of different types and structures. We are able to determine how additives affect the physical and mechanical properties of grey cement powder, as well as its workability; the fluidity, setting and hardening rates, and strength.
Atlas is ideal for a wide range of reactions and applications – such as calorimetry, and pH monitoring and control – at pressures of up to 3 bar; it can be reconfigured without the need for any tools, and its high chemical resistance enables processes to be performed in highly acidic or basic conditions. The repeatability and reliability of the reactions performed on the Atlas reactor, as well as the versatility of the system, are particularly useful when developing new compounds. Technical support and advice from both Syrris and Sithiphorn, our local distributor, are very good, and we were particularly pleased with the training and consultation service at the Syrris Thailand workshop. We are confident that the Atlas system will grow with us, as we add extra modules to meet our future requirements.”
