What is fundamental period of a building?
The fundamental building period is simply the inverse of the building frequency at the lowest harmonic - easy right? Basically, every system has a set of frequencies in which it "wants" to vibrate when set in motion by some sort of disturbance (in building design, typically a seismic or wind event) based on the system's mass and stiffness characteristics. The shortest frequency is known as the natural frequency. The inverse of frequency is the period of the system, and more specifically, the inverse of the natural frequency is the fundamental period.
What is the design life period of a road?
It is a period considered appropriate to the function of the road. An arbitrary design period (say 25 years) needs to be chosen to enable the design of the road pavement to be developed. The determination of the total traffic the road will experience is a function of the design life chosen, and an estimate of the steady traffic growth expected over that period (say 2%). The resulting Design Traffic calculation is then used to determine what thickness the pavement should be to handle the stresses exerted on it from road vehicles over 25 years. It is accepted that after 25 years the pavement will likely need some sort of rehabilitation or construction, and the design process starts over again.

How long do you keep concrete moist for curing?
Concrete should be kept moist for curing for at least 7 days. During this period, it’s important to maintain a consistent level of moisture, which can be achieved through methods like wet burlap, plastic sheeting, or curing compounds. In hotter or windy conditions, extending the moist curing period to 10-14 days may be beneficial to ensure optimal strength and durability. Proper curing enhances the concrete's hydration process and overall performance.
What is cement expiry period?
Cement doesn't really "expire". It may become ruined if it isn't kept properly, but it's basically powdered rock... it's kind of hard for it to "go bad" unless it gets moist or something and starts to set in the bag.
What are the best practices for preparing a high-quality concrete structure using Portland cement mix?
To prepare a high-quality concrete structure using Portland cement mix, it is important to follow these best practices: Use the correct ratio of Portland cement, aggregates, and water as specified in the mix design. Thoroughly mix the ingredients to ensure uniform distribution and proper hydration of the cement. Properly cure the concrete by keeping it moist and at the right temperature for an adequate period of time. Use good quality materials and ensure they are free from impurities that could weaken the concrete. Follow industry standards and guidelines for construction practices to ensure the structural integrity of the concrete.
