Microfine 20 is a very finely microcement. A common cement type that comply with EN 1971 is used as input material when Microfine 20 is manufactured. Microcements should be used in conjunction with related admixtures, used as a setting regulator suitable for demanding injection applications.
In specific grouting applications, such as for fine soils and finely cracked structures (rock or concrete), microfine cementbased grouts are often used instead of chemical grouts that were frequently used in the past. Different types of microfine cements are available, and their chemical and physical characteristics vary widely.
MICROCEM® is suitable for a range of applications, such as, cementbased repair compounds, injection grouting and soil stabilisation. The features of the MICROCEM® range of cements include: Based on Portland cement clinker with carefully selected set regulating additives. Contain no other additions
Waterproof concrete is an impermeable concrete used for longlasting, durable watertight construction. To improve the impermeability of the concrete, waterresisting admixtures can be added. Nevertheless, design and construction of a watertight concrete structure is a system approach, and waterproof concrete is only one element of it.
Chemical admixtures. Two superplasticizers (SP – naphthalenebased and melaminebased) were used at low W/C with cement A and microfine cement mixes (G, H, I, and J). The amount of SP used was between % and % by weight of cement.

CIP 15 Chemical Admixtures for Concrete WHAT are Admixtures? Admixtures are natural or manufactured chemicals which are added to the concrete before or during mixing. The most often used admixtures are airentraining agents, water reducers, waterreducing retarders and accelerators. WHY Use Admixtures?
Microfine Cement for Injection of Rock and Soil. DESCRIPTION MicroCem is a Portland cement based grouting material composed of microfine particles with a specific surface area of >800m²/kg. As a grout, it has excellent permeability, strength and durability properties.
Enables fluid cement grout mixtures to be formulated on the job site to accommodate specific site conditions. Compatible with various types of cement, including regular cement, high early strength cement, sulfateresistant cement and microfine cement, as well as with other grouting admixtures.
