DE NEEF® MC 500® MICROFINE® Cement is a blast furnace slag based cement composed of ultrafine particles, designed for injection into loose soils, rock, concrete, and downhole applications. DE NEEF® MC 500® has a grain size of d 95 equal to microns and a d 50 of microns. The composition is comparable to high sulfate – resistant ...
It is thus necessary to determine optimum SP and shrinkage reducing admixture (SRA) dosages for a microfine cement based grout. In this study, a saturation dosage was decided from two Polycarboxylate ether (PCE) based SPs in relation to neat cement using slump flow and rheological parameters.
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.
Cement is the main ingredient of cementbased grouts and its type should be determined according to the grain size distribution in the sitespecific project. This means that in coarse soils, Portland cement may be considered efficient, but as the soil grains become fine, other types of cement such as ultrafine, microfine, and superfine cements ...
Microfine Cement Grout: It is finely ground slag, fine fly ash, or Portland cement that are all mixed with water for allowing penetration into the fine cracks. Silica flume or any other fine pozzolana can be used with microfine The particulate size of microfine cement grout ranges from 6 to 10 microns.
Smart Mortacare is a chemical polymer modified cement admixture that is to be added to concrete mixtures to improve workability and strength by helping the cement to react and cure fully. Unless the mix is "starved" of water, the strength of concrete is inversely proportional to the amount of water added or watercement
Essential solutions for ready mix concrete. We make innovation concrete admixtures that enable you to meet the most challenging designs and performance requirements. Engineers choose our admixtures for concrete to build everything from the tallest skyscrapers to the largest infrastructure projects.
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.

The use of a variety of additives and admixtures in microfine and regular cementbased grout formulations has become routine in advanced professional grouting practice. They play an important role in producing more durable grouts with improved rheological and set characteristics than could be obtained using only neat cement suspension grouts.
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.

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.
TamCem 67 specially designed for precast concrete applications. It is a nonchloride liquid admixture which has been formulated to comply with the requirements of EN 9342 and ASTM C 494 for Type F high range water reducing/superplasticising admixtures. TamCem 67 is compatible with all cements meeting recognised international standards.
MICROFINE CEMENT GROUT LABORATORY TESTING AND RESULTS Introduction The purpose of the cement grout testing program was to determine if microfine cement grout mixes could be developed with the desired properties necessary for passive site remediation.
Spinor A12 is a product range of fine to ultrafine blast furnace slag binders with a maximum grain size distribution from 48 microns to 6 microns.
