Application

TEKNOCEM LA should be placed as a continuous pour to ensure maximum integrity of the repair. TEKNOCEM LA should be poured from one side of the shutter only so as to ensure that no voids occur as a result of air entrapment. If a tremie pipe is used to place the concrete, then the pipe should be placed at the bottom of the section that is to be repaired and slowly lifted upwards as the placement continues

Description

TEKNOCEM LA is a low-alkali highly fluid micro-concrete which has been specially formulated with non-ASR reactive aggregates to produce a high-quality fluid repair concrete. The product is mixed with clean water to produce a non-shrink repair concrete which is volume stable and does not segregate or bleed.

TEKNOCEM LA is suitable for use in thicknesses from 20–200 mm where a free-flowing self-compacting concrete is required. The product is easily mixed and may be placed by hand or pumped.
