Canobie Lake Park, a hand-built amusement venue in Salem, N.H., opened to the public in 1902 as a trolley park. The original visitor experience featured botanical gardens, a penny arcade, and a few early amusement rides. A wooden roller coaster named the Yankee Cannonball, built in 1936, still draws crowds 83-plus years later. In 1958, Canobie Lake Park was purchased by three close friends from New Jersey who decided to take on the challenge of renovating and revitalizing it themselves.

Crystalline waterproofing systems

Concrete News

Adi-Con CW Plus is a crystalline admixture whose proprietary reactive chemicals integrally waterproof concrete and mortar. Along with products of cement hydration, the chemicals spur formation of a nonsoluble gel throughout the matrix pores and capillary tracts. The admixture reduces concrete permeability; protects surfaces from chloride exposure and carbonation; and, reduces deterioration attributable to chemical attack and reinforcing steel corrosion.

Delo 600 ADF with Omnitax debuted last month as a heavy-duty engine oil product delivering maximum protection to both the engine and emissions system in on- or off-highway equipment. While current heavy-duty engine oils bear sulfated ash up to the American Petroleum Institute CK-4 limit of 1 percent, Delo 600 ADF is formulated to a 0.4 percent threshold, which helps drastically reduce the rate of diesel particulate filter clogging.

Cold weather concreting essential: Monitoring mix temperature

Concrete News

When placing in cold weather, extra precautions must be taken to ensure concrete sets properly and gains adequate strength. The Transtec Group, Texas-based concrete pavement practitioner, notes how the first few days after placement are the most important because that is when cement hydration reaction proceeds the fastest and concrete gains most of its compressive strength. However, cold conditions slow the hydration process, meaning that concrete placed in low temperatures gains less strength than the same mix in warmer temperatures during the same length of time. If the water in the concrete mix freezes, the hydration process stops completely. Even if it thaws, strength gain may not recover.
