- Acid formates for use as setting and early strength development . . .
Hydration of cement is a chemical change which is dependent on temperature Since ambient temperatures vary continually, an effective means of controlling the hydration rate is essential to the
- CIM - Introduction Aims - Grimsel
In the case of C-14, experimental work on the speciation of carbon during corrosion of activated and un-activated steel under anoxic conditions similar to that of an emplacement tunnel showed the formation of oxygenated and reduced hydrocarbons, including carboxylic acids and CH4
- Calcium Formate 101: Unlocking its Benefits and Applications
Calcium Formate is used in the construction industry as an additive to cement It acts as a setting accelerator, reducing the time it takes for cement to harden This is particularly useful in cold weather, where the low temperature can slow the setting process
- Improvement of Engineering Properties of Recycled Concrete Aggregates . . .
In this study, environmentally friendly and a cost-effective method is attempted to treat RCAs to improve its engineering properties In this method, RCAs were first soaked in a formic acid solution in which the formic acid reacts with cement hydration products attached to the surface of the RCAs
- Effect of different water-cement ratios on the durability of . . .
In this paper a study of the mechanisms of the destructive effect of acid on concrete tanks used on farms is presented It analyzed the extent and type of damage that occurred and demonstrated the possibility of preliminary detection of the problem also using unusual test methods such as sur-face morphology tests and SEM microstructural analysis
- Accelerator additive for cementitious compositions - Google Patents
The present invention relates to formic acid as a substantially chloride free accelerator additive for forming cementitious compositions which exhibit accelerated hardening, including
- US3619221A - Amine formate accelerator additives for portland cement . . .
Water-soluble salts of amines and formic acid are added to Portland cement compositions (e g concrete) to accelerate the setting time thereof The additives exhibit a particular
- Formic Acid: Properties, Reactions, Production and Uses
Methanoic acid, better known as formic acid, is the simplest carboxylic acid with the formula HCOOH It is a colorless, corrosive liquid with a pungent odor that is completely miscible with water and many polar solvents but only partially miscible with hydrocarbons Formic acid derives its name from ants (latin
