In order to enhance itscaking intensity, often greatly increases the cement the amount used,because its lime sand quite big (generally is 1: 1), this kind ofcaking mortar existence very big flaw, like brittleness oversized butflexibility insufficient, its compressive strength higher, but anti-booklet intensity and caking intensity lower and so on, the elasticitycoefficient higher distorts the ability to be very inferior.

为了提高其粘结强度，往往大大增加水泥的用量，由于其灰砂比较大(一般为1∶1)，这种粘结砂浆存在很大缺陷，如脆性过大而柔韧性不足，其抗压强度较高，而抗折强度和粘结强度较低等，弹性模量较高而变形能力很差等。

The results show that: the tensile strength, flexural strength and flexural modulus increase by about 10.4%, 62.1% and 122.3% respectively when the mass fraction of the aluminum powder increases from 0 to 50%, while elongation at break and impact strength decrease by about 65.0 and 74.4% respectively; the tensile strength, elongation at break and impact strength all increase with decreasing the particle sizes of the aluminum powders.b Nylon-12 coated metal powders for the indirect SLS process were prepared by the dissolution precipitation process. The coated powders have only 1.0 wt% nylon-12, and their SLS green parts have sufficient strength for features as small as 1.0 mm to be built and post-processed and high dimensional accuracy. The green parts were subjected to the post processing processes including binder decomposition and infiltration of epoxy resin, and then the metal/polymer composite parts with relatively high strength and accuracy were formed.At present, micron-scale inorganic fillers have been widely used to reinforce nylon SLS parts.
