ROADCEM HRB E3

GeneralROADCEM is a pioneering Hydraulic Road Binder in East Africa. It has been designed and developed with the intent to stabilise and improve physical and mechanical properties of soil in road construction works. It can also be used for waste stabilisation. It is ideal for treatment and stabilisation of road bases, sub-bases, capping layers, subgrades, platforms for parking, airstrip runways and more.

CharacteristicsProduct type: Hydraulic Road Binder: Compressive strength 22.5MPa (N/mm2) minimum.

Conformity: Manufactured to meet the physical and chemical requirements of BS EN 13282-1 (European Norm) standards.

Constituents: Clinker, Limestone Clinker, Pozzolana

Technical name: HRB E3 (Limestone based) - (Ex-Mombasa) HRB E3 (Pozzolana based) - (Ex-NGP)

Benefits• Longer open time of up to 6 hours

• Reduced probability of shrinkage cracks due to lower clinker content compared to OPC

• Reduced cost compared to OPC

• Can better adapt to specific job sites than OPC

• Lower carbon footprint formulations that aid in environmental sustainability

• Quality and reliability of a Bamburi brand

HANDLING AND STORAGETransport HRB in vehicles with adequate protection from humid weather. Store bagged HRB on timber pallets at least 10 cm above the floor in a dry building free from moisture or water. Stack HRB to a maximum height of 10 bags. Use HRB on a first in first out basis.

SOILS AND MIXING Use soil and materials that conform to relevant standards. Ensure accurate proportioning of all materials. Mix thoroughly until a homogenous mix is obtained.

WATER Use clean water without impurities (e.g. salts, grass, mud etc.) for soil treatment with HRB. Use the amount of water required as determined by laboratory trials. The use of excessive water adversely affects the soil treatment efficiency.

CURINGKeep HRB treated material damp for at least 7 days to prevent cracking and to ensure increase in strength. Cover the treated layer with polythene sheets or damp uncompacted gravel of 100mm minimum thickness.

HRB USAGEHRB should not have lumps. Poor quality soil materials and improper mix proportioning will significantly reduce the performance of treated soils. HRB can last over 90 days if handled and stored properly.

Conduct trial mixes with the ACTUAL soils to be used for treatment work. Conduct laboratory trials at soil testing laboratories before construction.

HEALTH AND SAFETY WARNING

• When working with HRB, wear safety glasses and gloves• Wash your hands after working with wet HRB• Wear a dust mask• Wear a safety helmet• In the event of HRB contact with eyes, rinse thoroughly with

water and get medical attention if necessary• Keep HRB out of reach of children

ApplicationsROADCEM is designed to provide optimal solutions for improving the engineering properties of soil:

• Strength and bearing capacity are increased

• Better volume stability by controlling swell and shrinkage – Better durability

• Modification of clay minerals enhances soil strength and bearing capacity

ROADCEM is suitable for:• Stabilisation of road base, sub-base and sub-grade materials and waste materials

• Treatment of soils with either low or moderate plasticity (it is especially suited to granular type materials with a lower PI)

• In situ (including deep lift) stabilisation or pugmill blending

Selection of the most suitable HRB type depending on the soil type can be validated using laboratory trials.
