I want to fill gaps between my patio paving flags.?

May 20, 2360 by robigouk | Posted in Garden & Landscape

I just washed my jet and patio slabs in my garden, and now when they meet there is a gap. I bought the ready mix concrete and I was told to brush? Is it really that easy?

Do not use use the concrete sand and cement mixture should be approximately 3:1 and that brush into the joints in a dry mixture.

Bald Eagles being extinct... Agree that it's a myth?

Occasionally, I grab a Canadian flag with something to say...
Want to "ay" with me?
I signed up as a lumberjack (to save the trees).
I paved the dirt beneath my feet;
I wanted to save the concrete.

They're not extinct at all. We have lots of them in northern Canada; they come here to nest. I've seen dozens of them this year. In the fall, when they're teaching the babies to fly, is very interesting. So, here's to the American Eagle; a bold and noble

Air-cleaning paving slabs assessed in Germany

Researchers resurfaced 1,000 square meters of a busy road with concrete paving stones that contained titanium dioxide (TiO2), a photocatalytic material that removes automobile-produced nitrogen oxides (NOx) from the air and converts them into... When the air was tested up to one-and-a-half meters above those stones, NOx levels were found to be 25 to 45 percent lower than above regular concrete on the same road. For the study, the length of that street is being covered with paving slabs coated with TiO2. Last month, we told you about an experiment with air-purifying concrete that was recently conducted in the Netherlands. Last year, at 55 percent of urban air monitoring stations in Germany, NOx levels over the maximum permissible limit were recorded....

Researchers Develop New Green Paving Slabs to Improve Air Quality ...

by Mike

Because the quality of the ambient air is not always good in urban areas because of road traffic, which is one of the primary sources of these emissions, in the city of Fulda the officials made a leap forward in eliminating pollution. Of course, the more intense the sunshine, the quicker the degradation of harmful substances, so our aim was to identify the formula with the highest photocatalytic efficiency rating. In German cities, toxic nitrogen oxide concentrations are exceeding maximum admitted levels, but this is about to change with the new innovative paving slabs reducing the amount of the nitrogen oxide in the air. On the  Petersberger Straße road, where the pollution level is 40 micrograms per cubic meter, some special slabs coated with titanium dioxide will convert the harmful substances such as nitrogen oxide into nitrates. “Experiments in Italian cities had already shown that photocatalytic paving slabs can improve the air quality....
