Have you seen any test results using temperature controlled concrete ingredients as a method of starting the curing process. On prior large project we used a local ready mixed company (Hawaii) where the ingredients would have been in the 70/75 F range, steam curing was added 1 hr later until temp was 140F, two 85 ton units were cast every day in each mold ( 12 hr Day ).


to 28 days of curing, the strength was also observed to increase with hydration period which inform non-deterioration of concrete. The results for the values of flexural strength range between 3.5N/mm² and 6.0N/mm² at 28days of curing.

CIP 11 - Curing In-Place Concrete WHAT is Curing? WHY Cure? Curing is the maintaining of an adequate moisture content and temperature in concrete at early ages so that it can develop properties the mixture was designed to achieve. Curing begins immediately after placement and finishing so


is significantly increased in concrete with a high water-to-cement ratio, low cement content, short curing period, low strength, and highly permeable or porous paste.


Effects of Non-Standard Curing on Strength of Concrete A Research Project at the NRMCA Research Laboratory – Series D 335 and D 338 By Karthik Obla, NRMCA Director of Research and Materials Engineering, Fernando Rodriguez, NRMCA Laboratory Manager and Soliman Ben-Barka, Senior Laboratory Technician


The strength of the concrete is related to the water to cement mass ratio and the curing conditions. A high water to cement mass ratio yields a low strength concrete. This is due to the increase in porosity (space between particles) that is created with the hydration process.


Curing is easy to skip in the instant but that will have a major impact on the quality of your finished work. While curing is important for all concrete, the problems that arise from not curing are most obvious with horizontal surfaces.


The effect of internal curing using pre-soaked lightweight aggregate in high-strength calcium sulfoaluminate cement concrete on shrinkage and internal humidity was investigated. Five mixture proportions with induced internal curing water (absorbed by lightweight aggregate) to cement (wIC/c) ratios of 0, 0·03, 0·06, 0·09 and 0·12 were …


At another plant I investigated, where diesel injectors were being remanufactured, the concrete floor had extensively deteriorated in areas where diesel oil had been spilling continuously for about 20 years.

Sep 21, 2007· How to Cure Concrete Curing concrete is the term used for stopping freshly poured concrete from drying out too quickly. This is done because concrete, if left to dry out of its own accord, will not develop the full bond between all of its ingredients.


This unique aspect of Solidia Concrete curing allows precise control of the curing process, permits the incorporation of a broad range of sands, aggregates and reinforcements, and enables concrete manufacturers to operate at higher speeds while minimizing material waste.


This guide reviews and describes practices, procedures, materials, and monitoring methods for the external curing of concrete and provides guidance for specifying curing procedures. Current curing techniques are presented and commonly accepted methods, procedures, and materials are described.


Here concrete specimens are cured under standard or other controlled conditions, and are used to maintain a specific curing or conditioning environment while studying curing-related properties, such as degree of hydration, maturity, and shrinkage (free, autogenous, chemical, and restrained).
