Parex Highway T-10
Parex Highway T-10 is a rapid setting concrete designed for reinstatement of all types of road and street furniture at ambient temperatures down to +1°C. The material hardens within five minutes and forms an initial set in around 10 minutes to allow continuation work. It can be hand mixed and is ideal for use by mobile repair teams. It incorporates graded aggregates and special non-shrink additives.
The rapid setting assists the fixing of highways furniture and fence posts. The product is chloride free and can be safely used with cast iron and steel units.
After placement no special curing is required in moderate ambient conditions.
A single pack mix with a low water requirement Parex Highway T-10 can be placed at up to 500mm thickness in a single pass and achieves a final compressive strength of 40N/mm².

Instructions for Use
Required mixing water is 1.0 to 1.75 litres. Aggregates as supplied contain moisture. Do not add excessive water for mixing.
Variations in water content for particular applications may alter concrete consistency and compressive strength achieved.
Laitance and all loose material including dust, oil and grease should be removed in order to produce a sound substrate. The work area should be pre-wetted taking care to remove any standing water before placing the Highway T10 concrete.
To achieve the most consistent concrete mix, mechanical mixing is recommended. Thorough hand mixing is suitable but care should be taken to ensure that the mix is fully wetted out without the use of excess water. Mechanical mixing may be carried out in a suitable vessel using a slow speed high torque drill and paddle. Hand mixing may be carried out using a clean spot board or wheelbarrow.
25kg of Parex Highway T-10 requires 1.0 to 1.75 litres of water to give a stiff concrete. Excess water should not be added. Combine the aggregate and cement portions and gradually add water until a stiff concrete consistency is achieved. Once setting of the concrete has commenced, further mixing should not be used to re-work the mix. The concrete should be placed within approximately 5 minutes of mixing. The working time may be extended in cold ambient conditions and may be slightly shortened in hot ambient conditions.
Place mixed concrete onto dampened prepared substrate as soon as possible after mixing. Compact concrete into place using a suitable tamp or float. Tools and mixers should be cleaned with water before the Parex Highway T-10 has hardened.
No special curing is required at temperatures between 5 and 35°C.
