18 Landscape Architect and Specifier News Bridge with Concrete Hands Attracts Hoards of Tourists A new landmark located in the Ba Na Hills of Vietnam, the Cau Vang Bridge, also called the Hands of the Gods Bridge, has tourists flocking to the breathtaking site. The bridge, built by Sun Group, has already gone viral on social media since opening in June. With two enormous concrete hands emerging from the forest floor and supporting the iridescent golden bridge, it is no wonder why so many people want pictures of the innovative structure. Stormwater Management through New Water-absorbing Concrete A surfacing material referred to as Topmix Permeable that can absorb 95 percent of water placed on it has recently been introduced. As reported by India Today, over 1,400 inches of water can permeate through this concrete per hour. Not only will the use of this material potentially help limit urban flooding, it also recharges local aquifers. The source does caution, however, that the level of water absorption may vary from area to area depending on particular climatic conditions. Concrete Pavement Sales Reach Post- Recession High For the seventh consecutive year, combined sales of segmental concrete pavement products in the U.S. and Canada have increased, according to the 2018 Industry Sales Profile, a survey of 26 manufacturers that represent 25% of the producing companies in the U.S. and Canada, released by the Interlocking Concrete Pavement Institute (ICPI). The survey found that sales growth was 2.8% in the U.S. and 0.2% in Canada among survey participants, compared to 2016 for all segmental concrete pavement products. According to the survey, products for residential use represented 77.9% of sales, while commercial applications comprised 12.5% of sales. Public/government and industrial sales were 8.2% and 1.4% respectively. New Concrete Repair Material Emerges from Canada Researchers from the University of Manitoba have been developing a material to restore cracked and damaged concrete pavement using a rehabilitation technique called partial depth repair. Mohamed Bassouni, professor of civil engineering at the university, states that the new repair mixes contain nano-silica, an ingredient that aids concrete repair in hydration, setting speed and strength. The research team took the materials to the streets of Winnipeg to test the effects of the mix, attaining success with their experiments. Bassouni is encouraged by the results and believes the new mix can change the way concrete pavement is repaired. BIA's New Website The Brick Industry Association has launched a new website that "delivers all things brick." The website offers comprehensive resources for new architects, builders, landscape professionals and more. The website includes a newsroom, an awards page and an exclusive page for members. Additionally, there are seven tabs that you can navigate to learn more about the brick industry: • Why Choose Brick? • Find Brick Professionals • Attend & Learn • Read & Research • Advocate for Brick • Pics of Brick • For the Homeowner "Our new website is clay brick central for the latest brick resources, ideas, education and information," said Ray Leonhard, BIA's president and CEO.

Study Researches Earthquake-proof Concrete A Ph.D., candidate in structural engineering at the University of Alberta is researching and testing high-performance concrete walls in order to create "earthquake-proof" concrete. In his tests, in which he recreates the effects of an earthquake, Mohammed Javad Tolou Kian uses concrete walls that contain two types of fibers, poly vinyl alcohol fibers and hooked-end steel fibers, for reinforcement. According to Tolou Kian, fiber reinforcement limits the formation of cracks by increasing the resistance of concrete. The fibers allow reinforced concrete walls to return to their original shapes and positions after the disruption of an earthquake. h a r d s c a p e n e w s
