ACI 305R-10: Guide to Hot Weather Concreting by ACI Committee 305

By ACI Committee 305

Environmental components, resembling excessive ambient temperature, low humidity, excessive wind, or either low humidity and excessive wind, impact concrete homes and the development operations of combining, transporting, and putting of the concrete fabrics. This consultant offers measures that may be taken to reduce the bad results of those environmental components and decrease the possibility of critical problems.

This advisor defines scorching climate, discusses capability difficulties, and provides practices meant to reduce them. those practices contain making a choice on fabrics and proportions, precooling parts, and batching. different issues mentioned comprise size of haul, attention of concrete temperature as positioned, amenities for dealing with concrete on the web site, and, in the course of the early curing interval, putting and curing suggestions, and acceptable checking out and inspection approaches in scorching climatic conditions. The fabrics, techniques, quality controls measures, and inspections defined during this record could be validated, monitored, or played as acceptable purely by means of contributors keeping the suitable ACI certifications or an identical.

This produced no discernible improvement in capsize resistance and, more surprisingly, only a marginal improvement in controllability when sailing downwind. A similar result, at least as far as capsize resistance goes, was found when the fin keel and traditional design were compared at the same weight and position of the centre of gravity. Neither design showed a discernible superiority, although of course the traditional design with its narrow beam and larger coachroof had a higher angle of vanishing stability, and therefore recovered more readily from the knockdown.

The IMS yacht, AFR Midnight Rambler, managed to avoid getting into trouble by displaying great skill. She also had the advantage of daylight; nevertheless, at the same time several roughly similar but larger designs were rolled and suffered severe structural damage. The 30-year-old design, Berrimilla, resolutely and intelligently crewed, found quite big trouble in the dark but somehow every time flipped upright and undamaged. The large, stiff, strong, well-preThe stricken VC Offshore Stand Aside with part of her coachroof ripped off.

6 406MHz EPIRBs should be the primary EPIRB. There should be one EPIRB per liferaft carried. HEAVY WEATHER SAILING 7 One waterproof handheld VHF should be carried in addition to the ship’s VHF. 8 Sheets of storm jibs and trysails should be permanently attached to the sail. 9 Four white parachute flares should be carried in addition to current flare requirements. 10 At least one of the ship’s batteries should be of the closed cell or gel type for the purpose of starting the engine after an inversion.
