To improve the durability of reinforced cement concrete structures, steps such as the reduction of watercement ratio by compatible admixtures, reduction of calcium hydroxide generation in the concrete by using supplementary cementitious material, and increase in the packing density of the paste component by using compatible microfine materials ...
National Concrete Masonry Association (NCMA). When grout is ordered from a ready mixed concrete producer, the specifications should be based on consistency and compressive strength. Converting loose volume proportions into batch weights per cubic yard is subject to .
MasterRoc MP 650 microfine portland cement is designed for use in rock and soil injection. MasterRoc MP 650 has a small particle size making it particularly well suited for penetration into tight joints, fissures and pore spaces.
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.
MICROFINE provides reduced water demand for a given workability, even up to 70% replacement level as per requirement of concrete performance. MICROFINE can also be used as a high range water reducer to improve compressive strength or as a super workability aid to improve flow.
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
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.

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.
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.

Spinor A12 consists of grains finer than 12 microns and 12 is the coarser grain size. Spinor A12 is manufactured at a dedicated manufacturing facility under close quality control specifications which guarantees optimized and ...
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.
