به نقل از سایت بتنو، همانطور که میدانید کشور ایران یک کشور زلزله خیز است و باید تمهیداتی اعمال شود برای بتن های آماده مطابق با استاندارد 6044 تمهیدات خاصی جهت معضلات فسادپذیری بتن، فاصله از مبدا و پمپ پذیر شدن بتن ارئه شده است. متاسفانه برای حل کاهش اسلامپ و کارایی بتن، به جای استفاده از روان کننده (کاهنده آب) به بتن آب زده می شود.
اکنون برای پیشگیری از افت اسلامپ و دوام سازه ها در برابر سولفاته شدن و کربناته شدن و چرخه های ذوب  ویخبندان و محل اتصال دال  وتیر وستون و از افزودنی های پوزولانی و روان کننده ها استفاده میشود.
طبق نشریه 479 مرکز تحقیقات ساختمان و مسکن یکی از راه های دستیابی به بتن توانمند برای رسیدن به مقاومت فشاری، کارایی و دوام مناسب، کاهنده قوی آب جهت کاهش نسبت آب به سیمان استفاده می شود.
