Chemical demolition does not entail big explosions and sticks of dynamite It is a process that relies upon expansive grout that is drilled into strategic areas of the concrete or rock to be removed As the chemical agent goes to work it expands creating cracks and fissures in the mass

Chemical testing includes oxide analyses SiO 2 CaO Al 2 O 3 Fe 2 O 3 etc to allow the cement phase composition to be calculated Type II cements are limited in C150M 85 to a maximum of 8 percent by mass of tricalcium aluminate a cement phase often abbreviated C 3 A which impacts a cement’s sulfate resistance

Chemical and physical tests were conducted on samples of cement cementsand mortar and concrete Compound composition was estimated through the chemical analysis of cement

Portland cement is a complex product made from very simple and abundant materials limestone and clay or shale Very precise proportions of these two basic materials have to be mixed with some additions to create a raw meal with a precise chemical composition this will result in the production of clinker through the complex pyroprocessing presented in Figure 31

This cement has a high resistance to various chemical attacks on concrete compared with ordinary portland cement and thus it is widely used It is used in marine structures sewage works sewage works and for laying concrete underwater such as bridges piers dams and mass concrete works etc

Portland cement concrete usually does not have good resistance to acids Some weak acids however can be tolerated particularly if the exposure is occasional There are essentially three ways to improve concrete’s resistance to acids 1 choosing the right concrete composition to make it as impermeable as possible 2 isolating it from the environment by using a suitable coating or 3

Cement is a fine powder obtained from the calcination at 1450°C of a mix of limestone clay and iron ore The product of the calcination process is clinkerthe main ingredient of cementthat is finely ground with gypsum and other chemical additives to produce cement Find out more about our main types of cement
