Premium Portland Pozzolana Cement is often recommended as the best cement for bridges and dams, and heavy engineering construction as it offers numerous advantages. This article delves into eight key benefits of using the best quality Portland Pozzolana Cement (PPC) from MAX Cement in your major engineering projects. 1. Enhanced Durability

The Homra pozzolanic cement pastes (I.0), with 20 wt.% Homra increases up to 7 days and then decreases with curing time. This is due to the pozzolanic reaction of Homra. Fig. 3. Chemically combined water contents of hardened cement pastes containing limestone instead of Homra. M. Heikal et al. / Cement and Concrete Research 30 (2000) 1827±1834 ...

Natural pozzolana, such as volcanic tephra and pumice, can be used as a partial replacement for cement in concrete production. This reduces the carbon footprint of concrete, aiding the industry's decarbonisation efforts. ... Challenges in research for using natural pozzolana as …

A cement substitute known as a direct cement replacement can substitute for Portland cement without requiring pozzolanic activity or reaction, and ground granulated blast furnace slag (GGBFS) is ...

Recently, Soares et al. [4] reported aspects of the kinetic and thermodynamic properties associated with pozzolanic activities of three types of nanoparticles of silica by using a method based on electronic sensors of pH.The authors concluded that their optimizations on Chapelle's method were useful to reveal aspects of the complex physical-chemistry of the …

In Portland pozzolana cement (PPC), the released Ca(OH)2 react with the pozzolana incorporated in the cement to produce more cementitous material. This lowers the concentration of CaO in the pore solution. For all the samples, the OH remains fairly constant at the 8th day of curing. This is because the pozzolanic reaction involves only the Ca ...

When natural pozzolana is added to a concrete mix up to 15 %, it generally acts as a filler material and helps in improving workability. It can enhance the flowability of the mix, allowing it to spread more easily and maintain a higher slump value. The pozzolana particles fill in the gaps between larger aggregate particles, creating a smoother ...
