Concrete

HHRM solutions for Special Applications make them the go-to company for difficult situations.

Non-Calcareous Concrete

For exposure to temperatures (circa 900°C) where limestone converts from Calcium Carbonate to Calcium Oxide (Lime) and CO2. Pumpable designs available.

Low Heat Heavyweight

Non-metallic mix designs (2600kg/m3 – 2900kg/m3) to ACI 349 for absorbing nuclear radiation (eg linear accelerators). Pumpable designs available.

Radiation-Shielding

Mix designs (2900kg/m3 – 3200kg/m3) for absorbing X-Ray Neutron Radiation from medical or industrial diagnostic equipment. Pumpable designs available.

Controlled Low Strength Materials

0.5N/mm2 – 8N/mm2 in accordance with ACI 229. Suitable for backfill where full compaction is needed and when re-excavation. Pumpable designs available.

Structural Lightweight Concretes

Using aggregate to ASTM C330/BS EN 13055 and Lightweight Foamed Concretes for Acoustic and Thermal requirements. Pumpable designs available.

High conductivity-Low Strength Fluidised Thermal Backfill

For HV Cable Protection. Pumpable designs available.

Mastering the use of non-standard aggregates and admixtures for high-tech applications makes design and supply of concrete for other purposes relatively simple. Project data and designs are available for almost every situation including the following.
