Slump Test

26 August 2010
Slump test is a test conducted before the concrete to be used for casting. The purposed of slump test is to determined the water content in concrete (whether it is too dry or too wet for concreting) and its workability.
Normally it is done for every mixer truck arrived. But it can also be detected by the movement of the wet concrete when it is being poured out to the bucket (when you familiar with it).
A slump can be collapse, or shear, when it is failed. A failed slump will need to be re-batching at the batching plant.
Equipment for slump test

Rectification for wall crack

It's time for me to share.
Today I'm gonna post something that I've learn in site. Information provided only for reference. Any wrong information that I given are welcome to post comment.
Wall crack usually happened when curing is not done properly casting. A correct method of rectification is very important to avoid structure failure, especially IBS that our site is using.

Today, I have my very first karate class teaches by Sensei Cyril Oh (one of the officer at Red Crescent). It begin with the day where we gather at Siew Ching's BBQ party when we discussed about it.
The Dojo located at YMCA, Damai. We were taught about stances and hoe to punch correctly. Well, hope I can be as good as Cyril one day.

Fishing for the first time…

7 August 2010
I went to fishing for the first time with my friend at site, which is Aminin and his wife, Nelson and Atan. I borrowed the fishing rod from my uncle and we went to our destination, under the Tuaran Bridge. I was so excited until I'm thinking of how many fished would I catch for the day, But pantang for me, I catched none. It wasn't our luck as the fishes won't eat our "already died bait". Lucky for Nelson, he cought two little fishes and gave it to me.
