In South Florida, we deal with many condominiums built as far back as the 1960s that have cast iron and have not yet set aside a budget for repair. If your building was built before 1985, you need to start budgeting for pipe repair now to avoid dishing out costly assessments in the case of sanitary sewer failure.Although the terms cement and concrete often are used interchangeably, cement is actually an ingredient of concrete. Concrete is basically a mixture of aggregates and paste. The aggregates are sand and gravel or crushed stone; the paste is water and portland cement. Concrete gets stronger as it gets older. Portland cement is not a brand name ... Oct 28, 2013 · In determining a more practical age for testing concrete strength, the 28-day myth began. So, while curing does help the hydration process, “28 days” is not an inclusive rule dictating a specific time to produce minimum compressive strengths. Simply stated, as the concrete cures and hydration takes place, the concrete gets stronger – and ... Importance of Curing. The curing protects the concrete surface from sun and wind. Curing imparts better strength to the concrete. The durability and impermeability of concrete are increased by proper curing. For the ordinary portland cement, the curing period is about 7 to 14 days.Since concrete is the most widely used manufactured material globally, the industrialized world faces billions of dollars in concrete testing and repair costs.

Conditions that cause high evaporation rates from the concrete surface, and thereby increase the possibility of plastic shrinkage cracking, include: Wind velocity in excess of 5 mph. Low relative humidity. High ambient and/or concrete temperatures. Small changes in any one of these factors can significantly change the rate of evaporation.Concrete Finisher Responsibilities: Setting forms that hold the concrete in place.
