Heat resistant concreteEverything About Concrete
At higher temperatures (above about 800 degrees F) high-heat-resistant concrete is generally needed. Light-weight aggregates have proven to be more heat resistant and so that is the first step--use lightweight. When temperatures get extremely high (above 1000 degrees F) calcium aluminate cement produces a fire-resistant concrete.
Lanko 5kg 156 High Temperature MortarBunnings Australia
A ready to mix mortar consisting of high temperature resistant alumnia cement and graded aggregates. Davco Lanko 156 High Temperature Mortar is ideal for pizza ovens fire places and barbecues. It is heat resistant up to 1000°C. It is ready to mix and can be used for new constructions or for patching.
Concrete Mix Design Controlling Temperature and Time
Fresh concrete temperature at the time of placing should be between 45 and 90 F. If heat or steam is used to assist in curing initial set should be achieved prior to the introduction of heat and/or steam. For this initial set should be recorded at a minimum of once per month per mix design to verify when the heat and/or steam can be introduced.
Heat Resistant Concrete or Refractory Concrete
Not only does the high temperature lead to decrease in steel-concrete bond and possibly melting at severe temperature but it can also cause concrete spalling and influencing steel properties. It is noted that the bond between concrete and steel decline at 300 o C temperature and if it is increased the concrete starts to spall and develop crack.

· High Temperature Concretes Refractory Castable cement. Castable refractory cement is a pre-mixed high temperature concrete. All one has to do is add water to it and mix it well. Once the mix solidifies it has very similar characteristics to fire bricks.
Effect of High Temperatures on Concrete Concrete
· High temperatures also affect the compressive strength of concrete. Above 212º F the cement paste begins to dehydrate (loses chemically combined water of hydration) which gradually weakens the paste and paste-aggregate bond. The temperature that concrete has reached often can be determined by observing color changes in the aggregate.

· Temperature also has a major effect on the setting time of concrete concrete placed under high temperatures will set quicker and can therefore require more rapid finishing. Concrete that is cured at high temperatures at an early age will not be as strong at 28 days as the same concrete
High temperature performance of wet-mix and dry-mix
· 2.2. Sample preparation. The wet-mix mortars were prepared according to the ASTM C305. Thermocouple was embedded into the center of the mortar samples (∅ 75 mm 150 mm) for measuring the temperature changes. To fix the position of the thermocouple they were tethered in the steel moulds using threads and the thermocouple wires were shielded by a ceramic insulator.

· To control the temperature of fresh concrete use 1- flaky ice up to70 of water as per ACI in some cases we can go upto100 in Makkah and madina we have done it. 2- zero temperature water. 3- Nitrogen ( Expensive) 4- adding fly ash by of cement. 5- Cooling the aggregates by shading and sparying cold water.
Properties of Concrete at Elevated Temperatures
Fire response of concrete structural members is dependent on the thermal mechanical and deformation properties of concrete. These properties vary significantly with temperature and also depend on the composition and characteristics of concrete batch mix as well as heating rate and other environmental conditions. In this chapter the key characteristics of concrete are outlined.
