Design of reinforced concrete structures is based on the 28 days strength of 15 cm cubes about 70% of which is attained at the end of the first week after placing. The final strength of concrete depends greatly on the conditions of moisture and temperature during this initial period. The maintenance of proper conditions during this period is known as curing. <\/p>\n\n\n\n<figure class=\"wp-block-image size-medium\"><img loading=\"lazy\" decoding=\"async\" width=\"300\" height=\"225\" src=\"https:\/\/www.zillionsbuyer.com\/blog\/wp-content\/uploads\/2020\/07\/What-is-the-Curing-process-of-concrete-300x225.jpg\" alt=\"\" class=\"wp-image-1531\" srcset=\"https:\/\/www.zillionsbuyer.com\/blog\/wp-content\/uploads\/2020\/07\/What-is-the-Curing-process-of-concrete-300x225.jpg 300w, https:\/\/www.zillionsbuyer.com\/blog\/wp-content\/uploads\/2020\/07\/What-is-the-Curing-process-of-concrete.jpg 602w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">About 30% of the strength can be lost by\npremature drying out of the concrete and similar amount may be lost by\npermitting concrete to drop to 2\u00b0C or lower during the first few days. To\nprevent such damage, concrete should be protected from loss of moisture for at\nleast 7 days. Curing can be done in several ways such as:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">(1) Moist curing which consists of the\napplication of water directly to the concrete or by means of continuously\nsaturated coverings of sand, straw or hessian etc.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">(2) Surface application of calcium chloride\nwhich not only absorbs moisture from the atmosphere but also prevents the\nevaporation of a part of the mixing water.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">(3) Membrane curing in which certain\nchemical compounds are applied to all exposed surfaces of concrete to form an\nimpervious film on the concrete which prevents the evaporation of moisture, <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">(4) The chemical reaction of hydration of cement can be accelerated under increased temperature which can be achieved by resorting to steam curing at atmospheric pressure. An efficient steam curing cycle depends on the pre-curing period, the rate of increase and decrease of temperature. The object of steam curing is to develop high early strength of concrete so that concrete products may be removed from the form work and handled as early as possible. It is mainly used in precast or prestressed concrete works.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Curing : Fresh concrete gains strength most rapidly during the first few days due to hydration of cement which can take place only in the presence of water.
