In the latter part of concrete small-sized hollow block masonry cracks after using many reasons, including the design factors that are not in place, the material factors, construction factors, climate, natural conditions, factors, etc., in which the age of c concrete small-sized hollow block length of cracks in the masonry of the impact is different. Cracks in the masonry structure will cause adverse effects, affecting the use of construction and durability, this paper field test, to identify non-instars of concrete small-sized hollow block masonry cracks on impact. To reduce or prevent age of concrete hollow block the effects of crack, to strictly control the construction of block wall on the age, age as long as possible, especially in areas influenced by temperature, such as wall, the top wall, should pay attention to blocks of age, in a possible, concrete hollow block age should be greater than 42 days, the best age to block more than 56 days is better.

Two evaluation models AHP / Fuzzy AHP were discussed and used for integrated assessment of highway landscape evaluation scheme, by initial AHP calculation of the weight of highway landscape evaluation factors, followed by the judgment matrix fuzzy calculation and evaluation. The results indicated that the more objective and scientific evaluation can provide a new method to evaluate highway landscape.
