the properties of class F high volume fly ash cement com-posite replacing 80 % of cement (Liu 2010; Huang et al. 2013). With the successful replacement of 80 % cement with supplementary cementitious materials, predominantly con-taining fly ash, the cement industry could benefit in signif-icantly reducing its CO 2 emissions, and at the same ...

This paper aims at investigating the influence of partial replacement of Portland cement with ultrafine fillers compared to limestone powder on the durability and mechanical characteristics of concrete. For this purpose, ultrafine calcium carbonate materials with different specific surface areas of 9.7 and 15.1 m2/g and limestone powder (0.72 m2/g) were used.

The ultrafine fly ash continues to increase the strengths and decrease the permeability as the concrete continues to cure beyond 28 and 56 days. This benefit was shown on the I-10 project through additional testing as the permeability dropped on some of the samples to as low as 150 coulombs. In addition, the use of an ultrafine fly ash for ...

MICROFINE CEMENT is a blast furnace slag-based ultrafine cement intended for specialty grouting applications. With a maximum particle size of ten microns and a median particle size of three microns, MICROFINE CEMENT is able to penetrate very small openings such as soil pores and microscopic rock fissures, in order to improve strength and reduce permeability.

Ultrafine Cement in Pressure Grouting presents the technical and practical information required by engineers to plan and implement grouting programs that are cost effective and technically sound. As a key component of modern grouting programs, ultrafine cement is an ideal solution for geotechnical engineers and construction contractors who are ...

Since ultrafine cement contains very fine particles, it is capable of invading narrow openings that other standard cement cannot access. In the literature ultrafine cement is defined as d. 95 < 10 microns which is very smaller compared to Type I Portland cement of 70 microns and Blaine fineness of at least 900 m. 2 /kg.

The cement industry has witnessed a steady growth in the market as different range of products using cement are manufactured. It is a binder, a raw material substance that serves as an adhesive to other materials. Cement mixed with water and fine aggregate produces mortar, sand and gravel to create concrete.

The aim of this experimental study was to investigate the penetrability of ultrafine Portland cement suspensions with or without additives into sand specimens and the strength and permeability of grouted sand samples. It was shown that ultrafine Portland cement grouts with dispersive agent could be used to treat not only medium to fine sand but also fine sand …

The present research is focused on the investigation of the influence of ultrafine additives on the structure formation of hardened cement paste and the establishment of the mechanisms of the morphological transformations, which determine the properties of hydrated products. In the course of the research, the modification of ordinary Portland cement was …

This was followed by injecting sand samples prepared in different gradations with ultrafine cement (UC) with and without SS additive. In the experiments, 1.0, 1.5, 2.0, and 2.5 were used as the water:cement ratios, and 1%, 3%, and 5% were used as the SS additive ratios. Unconfined compression tests were performed on the sand specimens that were ...
