<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><span style="color: green;">4、关于普通硅酸盐水泥主要特性的说法，正确的是（ ）。</span></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><span style="color: green;">A水化热较小</span></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><span style="color: green;">B抗冻性较差</span></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><span style="color: green;">C耐热性较差</span></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><span style="color: green;">D干缩性较大</span></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><span style="color: green;">答案：C</span></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><span style="color: green;">1解析</span></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><span style="color: green;">普通硅酸盐水泥（普通水泥）特性：凝结硬化比较快、早期强度较高、水化热较大、抗冻性较好、耐热性较差、耐腐蚀性较差、干缩性较小。</span></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><span style="color: green;">2理解</span></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><span style="color: green;">狂（矿渣）热 火神（渗）搞（高温）分（粉煤灰）裂</span></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><span style="color: green;">水泥的特性：水化热越大，抗冻性越好，耐热性越差。</span></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><span style="color: green;">矿渣颗粒大，渗水大。火山灰能抗热，水火不相容。</span></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><span style="color: green;">粉煤灰粉状细颗粒，不渗水，融合充分，结实，抗裂。</span></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><span style="color: green;">想想，放热多的话，一定是抗冻，同时，事物不是万能的，所以不抗热。</span></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><span style="color: green;">3拓展</span></p>
<p style="font-size: 18px; line-height: 40px; text-align: left; margin-bottom: 30px;"><span style="color: green;">普通硅酸盐水泥用P.O表示，你想，普通的都没有前途，所有是“0”</span></p>
