The Understanding Cement Blog

Welcome to the cement blog, perhaps the most interesting part of the site where cement science goes slightly less formal - this is jeans, tee-shirts and walking boots territory!

The pages in the main part of the site contain information that is, to the best of my knowledge, published, peer-reviewed and widely accepted.

In this blog there's cement science, but not necessarily peer-reviewed. For example, I describe experiments I've carried out. If it says "Blog" in red at the top of the page, just be a bit cautious! There may even be some opinion, anecdote and whimsy.

Over time, there should be something for everyone, with items on cement production, hydration, concrete, deleterious processes, cement history, analytical techniques and maybe some other stuff.

Many are short "mini-pages" although some are longer - just scroll down below and click on the links.

Note that new pages added to the articles in the site will also appear in the list below, so not everything listed here is a "Blog" item.

Updating of website pages

This website is being updated so that the pages are mobile-friendly. While doing this, the sequence of blog pots in the list below has got a bit scrambled, with some older posts appearing near the top of the list. This will sort itself out in due course but meanwhile, just scroll down to search the list!

Alkali-silica reaction ( asr ) and glass

Brief experiment to show that cement paste reacts with glass in a form of asr.
