How To Pour Concrete Over
A well-poured concrete slab with a deep, sturdy foundation can last for 30 to 40 years. pouring concrete over old concrete instead of directly over a new gravel foundation limits your ability to maximize the slab's lifespan. the condition of the existing slab is the primary factor that determines how long the new concrete will.According to this theory, concrete words are easier to remember than abstract words, because they activate perceptual memory codes in addition to verbal codes. schwanenflugel, harnishfeger, and stowe () presented an alternative context availability theory, according to which concrete words are easier to process because they are related.
